Table: des_sva1.gold_wlinfo
(The bold columns are indexed columns)
Column NameDescriptionDatatype
coadd_objects_idUnique object identifier (can be used to match against other SVA1 catalogs)BIGINT
dec_j2000Declination in decimal degrees (J2000)DOUBLE
htm9HTM index (order 9 => ~10 arcmin size)BIGINT
im3shape_flag0 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_gPhotometric magnitudes in g band. (mag = 99.0 indicates no detection in that band.)REAL
mag_auto_iPhotometric magnitudes in i band. (mag = 99.0 indicates no detection in that band.)REAL
mag_auto_rPhotometric magnitudes in r band. (mag = 99.0 indicates no detection in that band.)REAL
mag_auto_zPhotometric magnitudes in z band. (mag = 99.0 indicates no detection in that band.)REAL
mean_photozA point estimator of the photometric redshift for this object from the SkyNet photo-z catalog. (-99.0 if no point estimate is available.)REAL
nest256HEALPIX index (Nsides 256 => ~14 arcmin size)BIGINT
ngmix_flag0 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_binThe 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_j2000Right ascension in decimal degrees (J2000)DOUBLE
ring256HEALPIX index (Nsides 256 => ~14 arcmin size)BIGINT
sva1_flagA 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
