Table: des_sva1.gold_wlinfo
(The bold columns are indexed columns)
| Column Name | Description | Datatype |
|---|---|---|
| coadd_objects_id | Unique object identifier (can be used to match against other SVA1 catalogs) | BIGINT |
| dec_j2000 | Declination in decimal degrees (J2000) | DOUBLE |
| htm9 | HTM index (order 9 => ~10 arcmin size) | BIGINT |
| im3shape_flag | 0 if this object has a good im3shape shear estimate. 1 if not. This flag includes all cuts recommended for the im3shape catalog by Jarvis et al, 2015. cf. Section 9.1 and Appendix B. Using columns from the Im3Shape Catalog, this column is the following derived quantity: IM3SHAPE_FLAG = ~((ERROR_FLAG == 0) & (INFO_FLAG == 0) & (SNR_W > 15) & (MEAN_RGPP_RP > 1.2)) | INTEGER |
| mag_auto_g | Photometric magnitudes in g band. (mag = 99.0 indicates no detection in that band.) | REAL |
| mag_auto_i | Photometric magnitudes in i band. (mag = 99.0 indicates no detection in that band.) | REAL |
| mag_auto_r | Photometric magnitudes in r band. (mag = 99.0 indicates no detection in that band.) | REAL |
| mag_auto_z | Photometric magnitudes in z band. (mag = 99.0 indicates no detection in that band.) | REAL |
| mean_photoz | A point estimator of the photometric redshift for this object from the SkyNet photo-z catalog. (-99.0 if no point estimate is available.) | REAL |
| nest256 | HEALPIX index (Nsides 256 => ~14 arcmin size) | BIGINT |
| ngmix_flag | 0 if this object has a good ngmix shear estimate. 1 if not. This flag includes all cuts recommended for the ngmix catalog by Jarvis et al, 2015. cf. Section 9.1 and Appendix B. Using columns from the NGMix Catalog, this column is the following derived quantity: NGMIX_FLAG = ~((ERROR_FLAG == 0) & (0.4 < ARATE < 0.6) & (SENS_AVG > 0) & (SNR_R > 15) & (T_R / T_PSF > 0.15)) | INTEGER |
| photoz_bin | The cosmological photometric redshift bin (0, 1, or 2), as described in DES Collaboration, 2015. (-99 if unable to place in any bin due to other flags.) | INTEGER |
| ra_j2000 | Right ascension in decimal degrees (J2000) | DOUBLE |
| ring256 | HEALPIX index (Nsides 256 => ~14 arcmin size) | BIGINT |
| sva1_flag | A flag describing potential problems with this object prior to the shear estimation process. Only objects with SVA1_FLAG == 0 should be used for any scientific analysis. | INTEGER |
