1. AllWISE Atlas Metadata Table

Title:
AllWISE Atlas Metadata Table
Short Name:
AllWISE Metadata
Date:

Publisher:
NASA/IPAC Infrared Science Archive
Description:
The AllWISE program builds upon the work of the successful Wide-field Infrared Survey Explorer mission (WISE; Wright et al. 2010) by combining data from the WISE cryogenic and NEOWISE (Mainzer et al. 2011 ApJ, 731, 53) post-cryogenic survey phases to form the most comprehensive view of the full mid-infrared sky currently available. By combining the data from two complete sky coverage epochs using an advanced data processing system, AllWISE has generated new products that have enhanced photometric sensitivity and accuracy, and improved astrometric precision compared to the 2012 WISE All-Sky Data Release. Exploiting the 6 to 12 month baseline between the WISE sky coverage epochs enables AllWISE to measure source motions for the first time, and to compute improved flux variability statistics. The AllWISE Atlas Metadata Table contains brief descriptions of all metadata information that is relevant to the production of the Atlas images and Source Catalog. The table contains the (RA, DEC) of the center of the Tile. Much of the information in this table is processing-specific and may not be of interest to general users (e.g., flags indicating whether frames have been processed successfully or not, and the date and time of the start of the pipeline processing, etc.). The metadata table also contains some characterization and derived statistics of the coadd image Tile, basic photometric parameters used for photometry and derived statistics for extracted sources and artifacts.

5. IRAS Faint Source Catalog
ID:
ivo://irsa.ipac/IRAS/Catalog/FSC
Title:
IRAS Faint Source Catalog
Short Name:
IRAS-FSC
Date:
01 Oct 2018 20:27:21
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.
6. IRAS Point Source Catalog
ID:
ivo://irsa.ipac/IRAS/Catalog/PSC
Title:
IRAS Point Source Catalog
Short Name:
IRAS-PSC
Date:
01 Oct 2018 20:27:21
Publisher:
NASA/IPAC Infrared Science Archive
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.

9. NEOWISE 2-Band Post-Cryo Single Exposure (L1b) Known Solar System Object Possible Association List
ID:
ivo://irsa.ipac/WISE/Catalog/2-Band/SSOPAL
Title:
NEOWISE 2-Band Post-Cryo Single Exposure (L1b) Known Solar System Object Possible Association List
Short Name:
WISE 2-Band SSO
Date:
01 Oct 2018 20:27:16
Publisher:
NASA/IPAC Infrared Science Archive
Description:
The NEOWISE Post-Cryo Data Release products were generated using data taken during the mission's Post-Cryo survey phase. This phase covers the time following the exhaustion of solid hydrogen in the WISE payload inner cryogen tank, when the detectors and optics gradually warmed until they reached a stable equilibrium temperature near 73.5 K. During this time, WISE's W1 and W2 detectors continued to acquire high quality imaging data with sensitivities close to that during the mission's cryogenic survey phases. The W3 and W4 detectors were fully saturated by the thermal emission from the warming telescope. WISE scanned approximately 70% of the sky during the Post-Cryo survey phase continuing with the same strategy that was used during the full cryogenic survey. The Known Solar System Object Possible Associations List is a compendium of asteroids and comets, with orbits known at the time of WISE second-pass data processing, that were predicted to be within the field-of-view at the time of individual WISE exposures. Individual objects were observed multiple times, so may have multiple entries in the list. When the predicted position of a solar system object is in proximity to a detection in the WISE single-exposures, the WISE source position and brightness information are also provided.
10. NEOWISE 2-Band Post-Cryo Single Exposure (L1b) Source Table
ID:
ivo://irsa.ipac/WISE/Catalog/2-Band/SingleExpSourceTbl
Title:
NEOWISE 2-Band Post-Cryo Single Exposure (L1b) Source Table
Short Name:
WISE 2-Band ST
Date:
01 Oct 2018 20:27:16
Publisher:
NASA/IPAC Infrared Science Archive
Description:
The NEOWISE Post-Cryo Single-exposure Source Database contains 7,337,642,955 measurements of positions and brightness information, uncertainties, time of observation and assorted quality flags made on the individual WISE 7.7s (W1 and W2) Single-exposure images. Because WISE scanned every point on the sky multiple times, the Single-exposure Database contains multiple, independent measurements of objects on the sky. Entries in the Single-exposure Source Database include detections of real astrophysical objects, as well as spurious detections of low SNR noise excursions, transient events such as hot pixels, charged particle strikes and satellite streaks, and image artifacts light from bright sources including the moon. Many of the unreliable detections are flagged in the Single-exposure Database, but they have not been filtered out as they were for the All-Sky Release Source Catalog. Therefore, the Database must be used with caution. Users are strongly encouraged to read the Cautionary Notes before using the Database.
