Description:
The 'TNOs are Cool! - A Survey of the trans-Neptunian region' Open Time Key Program (KPOT_thmuelle_1) used PACS to observe 132 Centaurs and trans-Neptunian objects, as well as the giant planet irregular moon Sycorax.
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:
Spitzer IRAC Observations of the Extended Disk and Halo of M31 (M31 IRAC) covers the major and minor axes of M31 with total lengths of 6.6 and 4.4 degrees, respectively. The M31 IRAC Catalog includes 426,529 sources.
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.
IThe Japanese satellite-borne infrared telescope, the Infrared Telescope in Space (IRTS), surveyed about 7 per-cent of the entire sky in the infrared wavelengths from 1.4 to 700 um. The IRTS consists of a 15 cm telescope cooled with superfluid liquid helium, and is installed on board the Space Flyer Unit (SFU) spacecraft. The SFU was launched on 1995 March 18 UT. The sky survey by the IRTS started on March 29 UT, and was completed on April 25 UT after exhausting its liquid helium. The four focal-plane instruments were on board.
The Mid-Infrared Spectrometer (MIRS) covered 4.5 to 11.7 um by 32 spectral channels with the resolution of Δλ = 0.23-0.36 um. The MIRS point source catalog contains spectra of 536 sources. Many of the detected sources are mas-losing stars. A few HII regions and one asteroid 01 Ceres are included.

The Near-Infrared Spectrometer (NIRS) covered 1.4 to 4.0 μm by 24 spectral channels with the resolution of Δλ = 0.13 μm. The complete level of the catalog is 10?20 Jy for the entire wavelength range. The NIRS point source catalog contains spectra of 14,223 sources in which 4,002 sources are in good quality. Late-type stars, normal stars, and other red objects are included.
This is a view of the dust maps in the five orders, generated by
splitting the larger pixels from the higher orders into HEALPixes of
order 10. This means, in particular, that the spatial resolution for
all pixels with original_order!=10. Use this for convenient joins to
other tables.
