Abstract:
Crucial steps in the formation of stars and planets can be studied
only at mid- to far-infrared wavelengths, where the Space Infrared
Telescope (SIRTF) provides an unprecedented improvement in
sensitivity. We will use all three SIRTF instruments (Infrared Array
Camera [IRAC], Multiband Imaging Photometer for SIRTF [MIPS], and
Infrared Spectrograph [IRS]) to observe sources that span the
evolutionary sequence from molecular cores to protoplanetary disks,
encompassing a wide range of cloud masses, stellar masses, and
star-forming environments. In addition to targeting about 150 known
compact cores, we will survey with IRAC and MIPS (3.6-70µm) the
entire areas of five of the nearest large molecular clouds for new
candidate protostars and substellar objects as faint as 0.001 solar
luminosities. We will also observe with IRAC and MIPS about 190
systems likely to be in the early stages of planetary system formation
(ages up to about 10Myr), probing the evolution of the circumstellar
dust, the raw material for planetary cores. Candidate planet-forming
disks as small as 0.1 lunar masses will be detectable. Spectroscopy
with IRS of new objects found in the surveys and of a select group of
known objects will add vital information on the changing chemical and
physical conditions in the disks and envelopes. The resulting data
products will include catalogs of thousands of previously unknown
sources, multiwavelength maps of about 20deg2 of molecular clouds,
photometry of about 190 known young stars, spectra of at least 170
sources, ancillary data from ground-based telescopes, and new tools
for analysis and modeling. These products will constitute the
foundations for many follow-up studies with ground-based telescopes,
as well as with SIRTF itself and other space missions such as SIM,
JWST, Herschel, and TPF/Darwin.
Description:
This is the final delivery (DR4, Fall 2006 and Fall 2007) of the
Spitzer Space Telescope "From Molecular Cores to Planet-Forming Disks"
(c2d) Legacy Project. The data are also available as Enhanced Products
from the Spitzer Science Center (SSC). c2d has delivered 867 catalogs.
IRSA has merged these delivered catalogs into four groups - Clouds,
Off-Cloud, Cores, Stars - and serves them through the general catalog
search engine Gator. Many of the delivered catalogs, images and
spectra are accessible through IRSA's general search service, Atlas.
As a service to its users, the CDS has downloaded a dataset containing
most of the c2d data (but not all columns) from the IRSA archive. The
individual catalogs are listed below:
C2D Fall '07 Full CLOUDS Catalog (CHA_II, LUP, OPH, PER, SER)
C2D Fall '07 High Reliability (HREL) CLOUDS Catalog
(CHA_II, LUP, OPH, PER, SER)
C2D Fall '07 candidate Young Stellar Objects (YSO) CLOUDS Catalog
(CHA_II, LUP, OPH, PER, SER)
C2D Fall '07 Full OFF-CLOUD Catalog (CHA_II, LUP, OPH, PER, SER)
C2D Fall '07 candidate Young Stellar Objects (YSO) OFF-CLOUD Catalog
(CHA_II, LUP, OPH, PER, SER)
C2D Fall '07 Full CORES Catalog
C2D Fall '07 candidate Young Stellar Objects (YSO) CORES Catalog
C2D Fall '07 Full STARS Catalog
C2D Fall '07 candidate Young Stellar Objects (YSO) STARS Catalog
These tables have been merged into a single table at CDS.
All three SIRTF instruments (Infrared Array Camera [IRAC], Multiband
Imaging Photometer for SIRTF [MIPS], and Infrared Spectrograph [IRS])
were used to observe sources that span the evolutionary sequence from
molecular cores to protoplanetary disks, encompassing a wide range of
cloud masses, stellar masses, and star-forming environments.

Note (2): Some names in the original column 'Name' seem to be bugged,
like JHHMMSS.s+000-MMSS, JHHMMSS.s+000-MSS and JHHMMSS.s+00000SS.
The conventional (corrected) names are proposed in the CName column.
Note (3): the types are described in Section 2.5 of the delivery document;
keys to the classification are:
Zero = detected in one epoch only
2mass = 2MASS source without Spitzer detection
one = detected in only one band between IRAC1-3 (3.6 to 5.8µm)
two = detected in two bands, but not in IRAC4 (8um) and MIPS1 (24um)
red1 = detected only in IRAC-4 (8um) or MIPS-1 (24um)
red2 = detected only in IRAC-4 (8um) and MIPS-1 (24um)
star = main sequence or giant star
PAH_em = colors indicative of a peak in the 8um band
([3.6]-[4.5]<0.6 and [5.8]-[8.0]>1.5)
star+dust = SED consistent with a star and dust component; band specified as
e.g. star+dust(IR1) for an excess in IRAC-1 band (3.6um),
or star+dust(MP1) for an excess in MIPS-1 band (24um).
red = MIPS1 (24um) flux > 3 times the nearest IRAC band flux
YSOc = young stellar object candidate (can be combined with PAH-em,
red, star+dust)
GALc = galaxy candidate (can be combined with PAH-em, red, star+dust)
rising = rising SED (F(λ) increases with λ)
falling = falling SED ((F(λ) decreases with λ)
flat = flat SED
cup-up = concave SED
cup-down = convex SED
Note (4): Qualify flags from 2MASS (Cutri et al. 2003, Cat. II/246):
A=best; E=goodness-of-fit very poor; F=no reliable error estimate;
U=upper limit
Note (5): Quality flags of IRAC and MIPS detections:
A-E = detections with S/N ≥7 (A), ≥5 (B), ≥3 (C), ≥2 (D), <2 (E)
K = complex source (2 or more detections within 2arcsec in the same
band at the same epoch)
N = non-detections (outside the coverage in a band or within 2 pixels
of the edge of the mosaic)
U = upper limit
