Abstract:
The Spitzer Science Center and IRSA have released a set of Enhanced
Imaging Products (SEIP) from the Spitzer Heritage Archive. These
include Super Mosaics and a Source List (SL) of photometry for compact
sources. The primary requirement on the Source List is very high
reliability -- with areal coverage, completeness, and limiting depth
being secondary considerations. The SEIP include data from the four
channels of IRAC (3.6, 4.5, 5.8, 8 microns) and the 24 micron channel
of MIPS. The full set of products for the Spitzer cryogenic mission
includes around 42 million sources.
Description:
The Source List (SL) provides a list of highly reliable sources
extracted from the Spitzer imaging archive. The SL processing was
designed to prioritize reliability over completeness or areal
coverage. In order to make the Source list reliable, many sources were
rejected. As a result, it is not complete at any flux density. At
bright flux densities, nearby galaxies may be rejected for being too
extended, or for being too close to a neighboring galaxy. At faint
flux densities, sources will be missing because they do not meet the
signal-to-noise ratio cut or did not make the cuts in place for a
compact true source. Although the Source List is useful for many
science projects, users who require high levels of completeness are
encouraged to use caution.

--------------------------------------------------------------------------------
Note (1): The number of Spitzer bands that have ten-sigma detections (ap1 for
IRAC, PSF flux density for MIPS 24), plus 1 if there is a 2MASS
association, plus 1 if there is a WISE association.
Note (2): The type of measured flux density that is available for IRAC and MIPS.
0 = there is no IRAC/MIPS imaging data available and no flux densities are
available (no data).
1 = a 3-sigma source was detected in IRAC/MIPS, and measured flux densities
can be found in F*Ap or F*PSF columns (primary).
2 = there was not a ten-sigma source detected in IRAC/MIPS, but a >3-sigma
Bandfill flux density was measured at ra, dec and can be found
in *BF columns (bandfill).
3 = 3-sigma upper limits are recorded in the columns *lim (limit).
4 = the source is bright and detected in multiple bands, but fails to meet the
size criteria; this source is real, but its flux density cannot be
measured accurately, so it is not reported (extended source).
Note (3): Band flux flag as follows:
0 = the object lies in a normal region of the IRAC/MIPS channel Super Mosaic.
1 = the object lies in the vicinity of an extended source.
2 = the object lies in the vicinity of a bright source and possibly also an
extended source.
Note (4): The flux densities have not had an aperture correction applied.
For stellar point sources, multiply by 1.488. This column will be
non-null only if the PSF flux density detection is greater than 10 sigma.
Note (5): If a source is detected at >3 sigma within a 6 arcsec diameter
aperture, a PSF fit is attempted. However, if the best fit centroid
changes by more than 2 pixels (5 arcsec), only aperture flux densities
at the original position are reported. If a source is not detected at
>3 sigma in a 6 arcsec diameter aperture, only upper limits are reported.
Note (6): AORs that are in the same Observation Class and are spatially
contiguous are grouped into a Super Mosaic labeled with a single
identification number: SMID. The first digit of the SMID indicates the
Observation Class:
2 = zodiacal light
3 = Galactic Plane
4 = galactic
5 = extended sources
6 = extragalactic.
If a SuperMosaic is divided into multiple Regions (see REGID) then its
SMID will end in a 1. Otherwise, it will end in 0.
Note (7): If a Super Mosaic is larger than 0.25deg2, it is broken up
into 300x300 square arcminute Regions, with each Region overlapping
its neighboring Regions by 2.5 arcminute on all sides. The REGID
begins with the SMID followed by a "-" followed by a Tile Number.
For example, a REGID of 40002981-108 has an SMID of 40002981 and a
Tile Number of 108. Two sets of Regions per position are created for
IRAC data taken in High Dynamic Range (HDR) mode. The short frames are
assigned a REGID with a "-short" suffix. An example is 40002981-108-short.
Note (8): Contamination and confusion flag from II/311: 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 = Optical ghost. Source may be a spurious detection of or contaminated
by an optical ghost image caused by a nearby bright source
0 = Zero. Source is unaffected by known artifacts.
Note (9): Variability flag from II/311: 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 (10): Photometric quality flag from II/328:
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
w?snr>10.
B = Source is detected in this band with a flux signal-to-noise ratio
3<w?snr<10.
C = Source is detected in this band with a flux signal-to-noise ratio
2<w?snr<3.
U = Upper limit on magnitude. Source measurement has w?snr<2. The
profile-fit magnitude w?mpro is a 95% confidence upper limit.
X = A profile-fit measurement was not possible at this location in
this band. The value of w?mpro and w?sigmpro 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 w?sigmpro
will be "null" in this band. The value of w?mpro 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.
