- Description:
- The WISE 3-Band Cryo Data Release products are comprised of data taken during the mission's 3-Band Cryo survey phase. This phase covers the time following the exhaustion of solid hydrogen in the WISE payload outer cryogen tank, while the detectors and telescope were still cooled by the inner cryogen tank. During this time, WISE's W1, W2 and W3 bands were operational and continued to acquire useful data, but the W4 detector was saturated by thermal emission from the warming telescope. The sensitivity achieved in the W1 and W2 bands was similar to that during the full cryogenic mission phase. The W3 measurement sensitivity was degraded and decreased steadily during the 3-Band Cryo phase because of the increasing telescope temperature and decreasing exposure times. WISE scanned approximately 30% of the sky during the 3-Band Cryo survey phase continuing with the same strategy that was used during the full cryogenic survey. The following table contains brief descriptions of all metadata information that is relevant to the processing of Single-exposure (level 1) images and the extraction of sources from the corresponding Single-exposure images. The table contains the unique scan ID for a specific scan frame and the reconstructed right ascension and declination of the level 1b frame center. 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 or not, and the date and time for starting of the pipeline, etc.). The metadata table also contains some characterization and derived statistics of the Single-expsoure image frames, basic photometric parameters used for photometry and derived statistics for extracted sources and artifacts. For example, it contains median pixel values of the coadded sky coverage map, the number of sources with profile-fit photometry Signal-to-Noise (SNR) greater than 3, and the total number of real sources affected by artifacts such as electronic ghosts, etc.

- Description:
- The WISE 3-Band Cryo Single Exposure (L1b) Source Table contains positions and photometry in the 3.4, 4.6 and 12 μm bands for 3,703,319,374 sources extracted from observations made during the WISE 3-Band Cryo survey phase, 6 August 2010 through 29 September 2010. WISE scanned approximately 30% of the sky during this period when the telescope and focal planes operated at a slightly higher temperature, but were still cooled by solid hydrogen in the inner cryogen tank.

- Description:
- The WISE 3-Band Cryo Source Working Database (WDB) contains positions and photometry in the 3.4, 4.6 and 12 μm bands for 261,418,479 sources extracted from observations made during the WISE 3-Band Cryo survey phase, 6 August 2010 through 29 September 2010. WISE scanned approximately 30% of the sky during this period when the telescope and focal planes operated at a slightly higher temperature, but were still cooled by solid hydrogen in the inner cryogen tank. CAUTION: The 3-Band Cryo Source WDB is not a well-vetted, reliable list of infrared sources like the WISE All-Sky Release Source Catalog. The WDB contains both detections of real astronomical objects, as well as spurious detections of image artifacts, noise excursions, transient events such as cosmic rays, satellite trails and hot pixels. The WDB also contains redundant extractions of objects that fall in the overlap region between the 3-Band Cryo Atlas Tiles. The WISE 3-Band Cryo Source WDB is best used as a resource to learn more about objects that are found in the All-Sky Release Source Catalog. The 3-Band Cryo observations offer a second, independent epoch of measurement for objects in 30% of the sky, so can be used to test for object motion, flux variability and reliability in the case of very faint sources. 3-Band Cryo WDB entries have been cross-correlated with the All-Sky Catalog and associated Catalog source information is provided in the 3-Band Cryo WDB records.

- Short Name:
- WISEGalHII

- Publisher:
- NASA/IPAC Infrared Science Archive
- Description:
- The WISE Catalog of Galactic HII Regions consists of 8000 Galactic HII regions and HII region candidates selected by searching for their characteristic mid-infrared (MIR) morphology. WISE has sufficient sensitivity to detect the MIR emission from HII regions located anywhere in the Galactic disk. This is the most complete catalog yet of regions forming massive stars in the Milky Way. Of the ~8000 cataloged sources, ~1500 have measured radio recombination line (RRL) or Halpha emission, and are thus known to be HII regions. This sample improves on previous efforts by resolving HII region complexes into multiple sources and by removing duplicate entries. There are ~2500 candidate HII regions in the catalog that are spatially coincident with radio continuum emission. Previous RRL studies show that ~95% of such targets are HII regions. Approximately 500 of these candidates are also positionally associated with known HII region complexes, so the probability of their being bona fide HII regions is even higher. At the sensitivity limits of existing surveys, ~4000 catalog sources show no radio continuum emission. Distances for ~1500 catalog sources and molecular velocities for ~1500 HII region candidates are taken from the literature.

- Description:
- The YSOVAR (Young Stellar Object VARiability) Spitzer Space Telescope observing program obtained the first extensive mid-infrared (IRAC 3.6 and 4.5 micron) time series photometry of the Orion Nebula Cluster plus smaller fields in 11 other star-forming cores (AFGL 490, NGC 1333, Mon R2, GGD 12-15, NGC 2264, L1688, Serpens Main, Serpens South, IRAS 20050+2720, IC 1396A, and Ceph C). There are ~29,000 unique objects with light curves in either or both IRAC channels in the YSOVAR data set. YSOVAR is a sister project to the Coordinated Synoptic Investigation of NGC 2264 (CSI 2264; Cody et al. 2014). Initial YSOVAR results were described in Morales-Calderon et al. (2011). Rebull et al. (2014) describes the details of target selection, data reduction, and other conventions established for this project.
