Table: des_dr1.des_galex
(The bold columns are indexed columns)
| Column Name | Description | Datatype |
|---|---|---|
| angdist | Angular distance (arcsec) | DOUBLE |
| coadd_object_id | Unique identifier for the coadded objects | INTEGER |
| dec | Declination (ICRS) in DES catalog | DOUBLE |
| dec_cds | CDS declination (degrees) | DOUBLE |
| e_bv | The Galactic reddening expressed as E(B-V). This is derived from the Galactic extinctions maps from Schlegel et al. (1998, ApJ, 500, 525). Data obtained from http://astron.berkeley.edu/davis/dust/data/data.html | DOUBLE |
| fuv_artifact | Logical OR of artifact flags for pixels within a 3x3 pixel box in the FUV flags image centered on the source centroid pixel. The meanings of the flag values are the same as in the NUV. If no FUV observations are available at that location, then a value of -99.0 appears. | SMALLINT |
| fuv_flux | Calibrated FUV flux measured within the NUV-defined AUTO aperture. | REAL |
| fuv_fluxerr | The error in fuv_flux | REAL |
| fuv_mag | Calibrated FUV magnitude on the AB system measured within the NUV-defined AUTO aperture. Sources with either a negative FLUX_FUV or without FUV observations will be flagged with values of either +99 or -99. | REAL |
| fuv_magerr | The error in fuv_mag | REAL |
| nuv_artifact | Logical OR of artifact flags for pixels within a 3x3 pixel box in the NUV flags image centered on the source centroid pixel. The artifact flag is a binary flag with each bit indicating a different artifact. | SMALLINT |
| nuv_flux | Calibrated NUV flux. This is currently always set to the SExtractor AUTO flux. | REAL |
| nuv_fluxerr | The error in nuv_flux | REAL |
| nuv_mag | Calibrated NUV magnitude on the AB system. This is currently always set to the SExtractor AUTO magnitude. | REAL |
| nuv_magerr | The error in nuv_mag | REAL |
| objid | This is the 64-bit integer version of the global object ID uniquely identifying this source including the tile number, band, product number, reduction try (path), etc. | BIGINT |
| objtype | Object type | INTEGER |
| ra | Right ascension (ICRS) in DES catalog | DOUBLE |
| ra_cds | CDS right ascension (degrees) | DOUBLE |
