- Description:
- The Herschel Orion Protostar Survey (HOPS, KPOT_tmegeath_2) is a sample of 410 young stellar objects (YSOs) in the Orion molecular clouds, selected from Spitzer data. Most objects have near-infrared photometry from 2MASS, mid- and far-infrared data from Spitzer and Herschel, and submillimeter photometry from APEX; thus, the SEDs cover 1.2 - 870 microns and are used to classify the sample into protostellar classes. Of the 410 YSOs, 330 have Spitzer and Herschel data and are mostly protostars; the remaining objects include likely extragalactic contaminants and faint YSOs. Using mid-IR spectral indices and bolometric temperatures, the sample of 330 YSOs is classified into 92 Class 0 protostars, 125 Class I protostars, 102 flat-spectrum sources, and 11 Class II re-main-sequence stars. HOPS also implements a simple protostellar model (including a disk in an infalling envelope with outflow cavities) to generate a grid of 30,400 model SEDs and uses it to determine the best-fit model parameters for each protostar. This table contains the 2MASS, Spitzer, Herschel, and APEX source fluxes, as well as the rebinned IRS fluxes, of the 410 HOPS sources. Note that not every source has data at all of these wavelengths.

- Publisher:
- NASA/IPAC Infrared Science Archive
- Description:
- This new generation of IRAS images, called IRIS, benefits from better zodiacal light subtraction, calibration and zero levels compatible with DIRBE, and better destriping. At 100 microns, the IRIS product is also a significant improvement over the Schlegel et al. (1998) maps. IRIS keeps the full ISSA resolution, includes well calibrated point sources, and the diffuse emission calibration at scales smaller than 1 degree was corrected for the variation of the IRAS detector responsivity with scale and brightness. The uncertainty on the IRIS calibration and zero levels is dominated by the uncertainty of the DIRBE calibration and the accuracy of the zodiacal light model.

- Description:
- The IRAC Ultradeep Field (IUDF) combines all ultradeep data ever taken with the Spitzer Infrared Array Camera (IRAC) at 3.6 and 4.5 microns over GOODS-South and the HUDF (+ parallels). The deepest observations come from the IRAC Ultra Deep Field (IUDF, ID 70145, PI Labbe) and IRAC Legacy over GOODS (IGOODS, PID 10076, PI Oesch) programs, combined with archival data from GOODS (PID 194, PI Dickinson), SEDS (PID 60022, PI G. Fazio), S-CANDELS (PID 70204, PI Fazio), ERS (PID 80217, PI Fazio), and UDF2 (PID 30866, PI Bouwens). The combined IRAC images in this data release amount to 1500 hour total integration time, ranging from >50 hour over 150 sq. arcmin, and >100 hour over 60 sq. arcmin, to ~200 hour over 5 - 10 sq. arcmin.

- Publisher:
- NASA/IPAC Infrared Science Archive
- Description:
- The Faint Source Survey (FSS) is the definitive IRAS data set for faint point sources. The FSS was produced by point-source filtering the individual detector data streams and then coadding those data streams using a trimmed-average algorithm. The resulting images, or plates, give the best estimate from the IRAS survey data of the point source flux density at every surveyed point of the sky. The Faint Source Catalog (FSC) is a compilation of the sources extracted from the FSS plates that have met reasonable reliability requirements. Averaged over the whole catalog, the FSC is at least 98.5% reliable at 12 and 25 microns, and ~94% at 60 microns. For comparison, the IRAS Point Source Catalog (PSC) is > 99.997% reliable, but the sensitivity of the FSC exceeds that of the PSC by about a factor of 2.5. The FSC contains data for 173,044 point sources in unconfused regions with flux densities typically greater than 0.2 Jy at 12, 25, and 60 microns and greater than 1.0 Jy at 100 microns.

- Publisher:

- Description:
- This is a catalog of 245,889 well-confirmed point sources, i.e., sources with angular extents less than approximately 0.5', 0.5', 1.0', and 2.0' in the in-scan direction at 12, 25, 60, and 100 µm, respectively. Positions, flux densities, uncertainties, associations with known astronomical objects and various cautionary flags are given for each object. While two other complementary data sets - the Working Survey Database and the Point Source Reject Catalog - give information about point-like sources, the information available in the Point Source Catalog should satisfy almost all users. Away from confused regions of the sky, the survey is complete to about 0.4, 0.5, 0.6, and 1.0 Jy at 12, 25, 60, and 100 µm (cf. Faint Source Catalog). Typical position uncertainties are about 2" to 6" in-scan and about 8" to 16" cross-scan. The processing steps applied to detect and confirm point sources, and the positional and photometric error analyses are described in the Explanatory Supplement. The sources appear in order of increasing (1950.0) right ascension.
