SpIES Catalog Definitions

Overview

The Spitzer IRAC Equatorial Survey (SpIES) is a large-area survey of 115 sq. degrees in the Equatorial SDSS Stripe 82 field. SpIES achieves 5 sigma depths of 6.13 microJy (21.93 AB magnitude) and 5.75 microJy (22.0 AB magnitude) at 3.6 and 4.5 microns, respectively.

The 3.6 micron catalog contains the 6.1 million sources that are only detected at 3.6 microns, the 4.5 micron catalog contains the 6.4 million sources that are only detected at 4.5 microns, and the Dual-band catalog contains the 5.4 million sources that are detected in both bands.
