Photometric catalog contents.
| Name | Description |
| id_IAU | Object name, according to IAU standards: prefix VIPERS plus internal identification number. |
| num | Internal id number (num) in the form attxxxxxx where a identifies the sky area (1 for W1 and 4 for W4), tt identifies the CFHTLS tile number where the object is located, xxxxxx is the original CFHTLS ID within the tile. |
| alpha | J2000 Righ Ascension in decimal degrees. |
| delta | J2000 Declination in decimal degrees. |
| selmag | iAB selection magnitude. The selection magnitude comes from CFHTLS T0005 catalogues. |
| errselmag | Error on the selection magnitude. |
| u,g,r,i,z | Magnitudes (AB system) from the CFHTLS T0005 catalogue, supplemented by T0006 catalogue in some specific cases (see Guzzo et al. 2013, Sect. 3 and Appendix C, for details on the tile to tile color offests, as well as for T0005 and T0006 catalogue differences). All magnitudes are corrected for Galactic extinction. When an object has not been observed in a given band, magnitude and error are set equal to −99. When a magnitude (and its error) could not be measured, these values are set to 99. |
| erru,errg,errr,erri,errz | Errors on CFHTLS05 magnitudes. |
| uT07,gT07,rT07,iT07,zT07 | Magnitudes (AB system) from the CFHTLS T0007 catalogue. All magnitudes are corrected for Galactic extinction. |
| erruT07,errgT07,errrT07,erriT07,errzT07 | Errors on CFHTLS T0007 magnitudes. |
| DeltaUG, DeltaGR, DeltaRI | Tile to tile color offsets used in the targets sample selection applied to the CFHTLS T0005 data (see Guzzo et al. 2013, Sect. 3.1). |
| E BV | Extinction factor E(B − V) derived from Schlegel’s maps. |
| r2 | Radius enclosing half the object light as from CFHTLS T0005 catalogue, in pixels. |
| r2T07 | Radius enclosing half the object light as from CFHTLS T0007 catalogue, measured in pixels. |
| classFlag | VIPERS selection flag based on the CFHTLS T0005 catalogue (see Guzzo et al. 2013, Sect. 4). |
| agnFlag | A value equal to 1 is assigned to all AGN candidates, and equal to 0 otherwise (see Sect. 2.2). |
| photoMask | Flag indicating whether the object falls within the photometric mask: 1 if the object is inside the mask, 0 if it is outside. |
| spectroMask | Flag indicating whether the object falls within the spectroscopic mask: 1 if the object is inside the mask, 0 if it is outside (see Sect. 6.1). |
