Abstract:
We have conducted a study of star formation in the outer Galaxy from
65°<l<265° in the region observed by the GLIMPSE360 program.
This Spitzer warm mission program mapped the plane of the outer Milky
Way with IRAC at 3.6um and 4.5um. We combine the IRAC, Wide-field
Infrared Survey Explorer (WISE), and Two Micron All Sky Survey
catalogs and our previous results from another outer Galaxy survey and
identify a total of 47,338 young stellar objects (YSOs) across the
field spanning >180° in Galactic longitude. Using the DBSCAN
method on the combined catalog, we identify 618 clusters or
aggregations of YSOs having five or more members. We identify
10,476 class I, 29,604 class II, and 7325 anemic class II/class III YSOs.
The ratio of YSOs identified as members of clusters was 25,528/47,338,
or 54%. We found that 100 of the clusters identified have previously
measured distances in the WISE H II survey. We used these distances in
our spectral energy distribution (SED) fitting of the YSOs in these
clusters, of which 96 had YSOs with <3σ fits. We used the
derived masses from the SED model fits to estimate the initial mass
function (IMF) in the inner and outer Galaxy clusters; dividing the
clusters by galactocentric distances, the slopes were
Γ=1.87±0.31 above 3M☉ for RGal<11.5kpc and
Γ=1.15±0.24 above 3M_☉ for RGal>11.5kpc. The slope of
the combined IMF was found to be Γ=1.92±0.42 above 3M☉.
These values are consistent with each other within the uncertainties
and with literature values in the inner Galaxy high-mass star
formation regions. The slopes are likely also consistent with a
universal Salpeter IMF.
Description:
The GLIMPSE360 survey completes the coverage of the Galactic plane
that began with the earlier GLIMPSE surveys, and its catalog (II/293)
contains a total of 49,378,042 sources. The observations were taken as
part of a Spitzer Warm Mission Exploration Science program and
performed using the two short-wavelength IRAC bands at 3.6 and 4.5um.
The IRAC observations were obtained in High Dynamic Range mode, which
was comprised of three visits per mosaic position with 0.6 and 12s
integrations, similar to the Spitzer Mapping of the Outer Galaxy
(SMOG) survey.
The SMOG survey (J/ApJ/880/9) data consist of the SMOG Catalog, with
2,512,099 high-reliability point sources, and the SMOG Archive, with
2,836,618 sources with less stringent selection criteria. These
contains IRAC observations at 3.6, 4.5, 5.8, and 8.0um.
The mid-IR photometry was supplemented by J-, H-, and Ks-band
photometry from the Two Micron All Sky Survey (2MASS) point-source
catalog (II/246). The photometric catalogs were merged using a
1.6" matching radius.
The Wide-field Infrared Survey Explorer (WISE) provides mid-IR
photometry at 3.4, 4.6, 12, and 22um. The AllWISE catalog (II/328) is
an all-sky survey combining the cryogenic WISE all-sky survey (II/311)
and the NEOWISE postcryogenic survey. Selection of all of the sources
in the GLIMPSE360 field was made, resulting in a regional catalog of
14,483,596 point sources. The WISE satellite has a highest resolution
of ∼6.1" at 3.5um. However, the astrometric accuracy and matching to
the 2MASS catalog are to within 1.5", so we performed catalog matching
to the GLIMPSE360 catalog at 1.5".
The merging of these datasets gives the Star Formation in the Outer
Galaxy (SFOG) catalog.

Note (1): This column is a merge of the original "designation" and
"designation_1" columns. The two separated columns were an artifact
of the way the catalog was assembled using different databases, and
the merge was done with the authors' authorization.
The object identifiers can start with the acronym SSTGLMA (GLIMPSE360
database) or SSTSMOGA (SMOG database). GLIMPSE stands for Galactic Legacy
Infrared Mid-Plane Survey Extraordinaire and SMOG stands for Spitzer
Mapping of the Outer Galaxy.
The objects with an identifier starting with "J" are WISE sources with no
IRAC data.
Note (2): The close source flag is set if there are Archive sources that are
within 3" of the source. Flags are as follows:
0 = no Archive source within 3.0" of source
1 = Archive sources between 2.5" and 3.0" of source
2 = Archive sources between 2.0" and 2.5" of source
3 = Archive sources between 1.5" and 2.0" of source
4 = Archive sources between 1.0" and 1.5" of source
5 = Archive sources between 0.5" and 1.0" of source
6 = Archive sources within 0.5" of source
Note (3): The value of the SQF is Σ2(bit-1). For example, a source with
bits 1 and 4 set will have SQF=20+23=9. If the SQF is 0, the source
has no detected problems. On the other hand, a source with SQF=29360128
has a corresponding binary number of 000001110000000000000000000000,
meaning the source has bits 23, 24, and 25.

where
X - There is a detection at this location, but no valid brightness
estimate can be extracted using any algorithm.
U - Upper limit on magnitude. Source is not detected in this band or it is
detected, but not resolved in a consistent fashion with other bands.
F - This category includes sources where a reliable estimate of the
photometric error could not be determined.
E - This category includes detections where the goodness-of-fit quality of
the profile-fit photometry was very poor, or detections where psf fit
photometry did not converge and an aperture magnitude is reported, or
detections where the number of frames was too small in relation to the
number of frames in which a detection was geometrically possible.

----------------------------------------------------------------------------
Therefore, in the previous example, the source with SQF=29360128 has a
photometric quality A flag from 2MASS-PSC.
For more information, please refer to the following documentation:
https://irsa.ipac.caltech.edu/data/SPITZER/GLIMPSE/doc/glimpse360dataprodv1.5.pdf (Table 5)
https://irsa.ipac.caltech.edu/data/SPITZER/GLIMPSE/doc/smogdataprodv1.1.pdf (Table 4)
Note (4): CAUTION - Note concerning "proper" motions: according to AllWISE
documentation, the motions measured are not proper motions because
they are affected by parallax motions. More information is given in:
http://wise2.ipac.caltech.edu/docs/release/allwise/expsup/sec2_6.html#HowToInterpret
Note (5): Five character string that encodes information about factors that
impact the accuracy of the motion estimation. These include the
original blend count, whether a blend-swap took place, and the
distance in hundredths of an arcsecond between the non-motion
position and the motion mean-observation-epoch position. The format
is NQDDD where N is the original blend count, Q is either "Y" or "N"
for "yes" or "no" a blend-swap occurred (i.e., the original primary
component was not the final primary component), and DDD is the radial
distance between the non-motion and motion at mean-observation epoch
positions in units of 0.01 arcsec, clipped at 999 (almost 10 arcsec).
Note (6): One character per band (W1/W2/W3/W4) that indicates that the
photometry and/or position measurements of a source may be
contaminated or biased due to proximity to an image artifact:
D,d = Diffraction spike. Source may be a spurious detection of or
contaminated by a diffraction spike from a nearby bright star on the
same image
P,p = Persistence. Source may be a spurious detection of or contaminated by
a latent image left by a bright star
H,h = Halo. Source photometry may be a spurious detection of or contaminated
by the scattered light halo surrounding a nearby bright source
O,o = (letter "o") Optical ghost. Source may be a spurious detection of or
contaminated by an optical ghost image caused by a nearby bright source
0 = (number zero) Source is unaffected by known artifacts.
Note (7): Extended source flag as follows:
0 = The source shape is consistent with a point-source and the source is
not associated with or superimposed on a 2MASS XSC source 1.
1 = The profile-fit photometry goodness-of-fit, chi2W?, is >3.0 in one or
more bands.
2 = The source falls within the extrapolated isophotal footprint of a
2MASS XSC source.
3 = The profile-fit photometry goodness-of-fit, chi2W?, is >3.0 in one or
more bands, and The source falls within the extrapolated isophotal
footprint of a 2MASS XSC source.
4 = The source position falls within 5" of a 2MASS XSC source.
5 = The profile-fit photometry goodness-of-fit, chi2W?, is >3.0 in one or
more bands, and the source position falls within 5" of a 2MASS XSC
source.
Note (8): The variability flag is a 4-character string, one character per band,
containing a value related to the probability that the source flux
measured on the individual WISE exposures is variable.
- value "n" indicates insufficient or inadequate data to make a
determination (<6 exposures)
- values 0 thru 9 indicate increasing probabilities of variation
- values 0-5 are most likely not variable
- values 6-7 are likely variables (but susceptible of false-positive
variability)
- values >7 have the highest probability of being true variables
Note (9): Four character flag, one character per band (W1/W2/W3/W4), that
provides a shorthand summary of the quality of the profile-fit
photometry measurement in each band, as derived from the measurement
signal-to-noise ratio:
A = Source is detected in this band with a flux signal-to-noise ratio
snr?>10.
B = Source is detected in this band with a flux signal-to-noise ratio
3<snr?<10.
C = Source is detected in this band with a flux signal-to-noise ratio
2<snr?<3.
U = Upper limit on magnitude. Source measurement has snr?<2. The
profile-fit magnitude W?mag is a 95% confidence upper limit.
X = A profile-fit measurement was not possible at this location in this
band. The value of W?mag and e_W?mag will be "null" in this band.
Z = A profile-fit source flux measurement was made at this location, but
the flux uncertainty could not be measured. The value of e_W?mag will
be "null" in this band. The value of W?mag will be "null" if the
measured flux, W?Flux, is negative, but will not be "null" if the flux
is positive. If a non-null magnitude is present, it corresponds to the
true flux, and not the 95% confidence upper limit. This occurs for a
small number of sources found in a narrow range of ecliptic longitude
which were covered by a large number of saturated pixels from 3-Band
Cryo single-exposures.
Note (10): Integer frame detection count. This column gives the number of
individual 7.7s exposures on which this source was detected with
SNR>3 in the W? profile-fit measurement. This number can be zero for
sources that are well-detected on the coadded Atlas Image, but too
faint for detection on the single exposures.
Note (11): Number of individual 7.7s W? exposures on which a profile-fit
measurement of this source was possible. This number can differ
between the four bands because band-dependent criteria are used to
select individual frames for inclusion in the coadded Atlas Images.
This column is null if there is no frame coverage in this band at
the position of this source.
Note (12): These objects are from a crossmatch of the IRAC and AllWISE
databases, with their AllWISE identifiers given here and their
other source designations given in the "Source" column.
Note (13): For example, a source detected in W1 only has fdet=1 (binary 0001).
A source detected in W4 only has fdet=8 (binary 1000). A source
detected in all four bands has fdet=15 (binary 1111).

Note (1): Paper I (Winston+2019, J/ApJ/880/9) compared the photometry in IRAC
bands 1 and 2 and WISE bands 1 and 2 for sources matched to within

the uncertainties. The combined IRAC+WISE data set uses photometry
from the two available IRAC bands to replace the appropriate WISE
band fluxes where the sources matched to within 1.5".
Note (2): The cluster number of the YSO is indicated in this column.
See Table 4.
A "-1" indicates that there was no cluster affiliation identified.
Note (3): The numerical YSO class, as described in Section 3.4.1., which
depends on the slope, α, of the spectral energy distribution
across the mid-IR bandpasses. Classes as follows:
1 = Class 0/I: protostellar objects with a rising slope, α>0;
(10476 occurrences)
2 = Class II: characterized by decreasing slopes in the range -1.6<α<0;
(29604 occurrences)
3 = Class IIa/III: class IIa sources lack optically thick emission from
a disk and possess decreasing slopes α←1.6, consistent with a
weak emission above a stellar photosphere. Truly diskless class III
objects show slopes in the range -2.7<α←2.0;
