Taurus Catalog October 2008 v2.1 Definitions
Taurus Overview
The Spitzer Space Telescope Survey of the Taurus is a Legacy III project titled, Taurus 2: Finishing the Spitzer Map of the Taurus Molecular Clouds (Taurus). The Taurus Spitzer Legacy project has mapped ≈44 square degrees of the Taurus star-formation region using the IRAC and MIPS cameras aboard the Spitzer Space Telescope. In this release, the team provides a bandmerged catalog of 269,358 point sources for the initial 70% of the survey area ("Taurus 1"). Flux densities are reported for the 3.6, 4.5, 5.8, 8.0, and 24 micron bands of IRAC and MIPS. MIPS 70 micron flux densities are also given for a small number of sources. Aperture photometry at three radii is provided for IRAC sources. PSF-fitting photometry is reported for MIPS flux densities.
The Taurus project page can be found here. Also provided with the data release is the Taurus data delivery documentation.
Taurus IRAC/MIPS Catalog October 2008 v2.1 Column Descriptions
Gator serves the Taurus Catalog October 2008 v2.1 (48 columns [43 delivered + 5 IRSA-created], 269,358 data rows). The following abbreviations are used in the Taurus catalog for Spitzer instrument/band combinations:
- I1 = IRAC Band 1, 3.6 µm
- I2 = IRAC Band 2, 4.5 µm
- I3 = IRAC Band 3, 5.8 µm
- I4 = IRAC Band 4, 8.0 µm
- M1 = MIPS Band 1, 24 µm
- M2 = MIPS Band 2, 70 µm
- M3 = MIPS Band 3, 160 µm (listed for reference, no Taurus data for MIPS 160)
- -9 means no data available.
- ALL fluxes are in microJy
- MIPS fluxes are PRF-fitted fluxes.
- IRAC aperture fluxes (and errors) are reported for 2px, 5px, and 10 px. and are already aperture-corrected (apertures correspond to 2.44", 6.1", and 12.2" respectively, in arcseconds).
- The iracdf column means irac dropped friend - e.g., there was an object within 2 px of this object that was dropped from the original source list. The four integers correspond to four irac channels, so a value of 0100 means channel 2 had a source that was dropped before the bandmerger even saw it.
- IRAC photometry has been corrected for blue sources. Last 4 columns indicate multiplicative factor that was used.
