MUSYC Photometric Redshift Catalog Definition
MUSYC Overview
The Multiwavelength Survey by Yale-Chile (MUSYC) consists of deep optical medium-band and broadband optical and near-IR imaging of the ~30'x30' Extended Chandra Deep Field South. This field includes the GOODS-South field and the Hubble Ultra Deep Field, and covers the same area as the SIMPLE Spitzer Legacy program.
The MUSYC project page can be found here. Documentation for the data can be found in Cardamone et al. (2010), and a README for the catalogs is also available.
| Name | Intype | Units | Description |
|---|---|---|---|
| Num | int | Sequential Object Identifier | |
| ra | double | degree | Right Ascension (J2000) |
| dec | double | degree | Declination (J2000) |
| xr_flag | int | X-ray counterpart flag: value = 1 if detected source is an X-ray Counterpart (Cardamone et al. 2008) X-ray counterparts included an additional QSO template when finding redshift solutions and rest-frame colors in EAzY |
