Table 8
Spectral 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. |
| zspec | Spectroscopic redshift. A conventional zpsec value of 9.9999 is assigned in case a redshift could not be measured. |
| zflg | Redshift confidence flag as described in Sect. 4.3. |
| epoch | Observing epoch: epoch = 1 objects have been observed before VIMOS refurbishing in summer 2010, epoch = 2 objects have been observed after summer 2010. |
| photoMask | Flag indicating whether the object falls within the photometric mask. 1 if the object is inside the mask, 0 if it is outside. |
| tsr | Target sampling rate as described in Sect. 6.2. TSR is =−1 for serendipitous targets (flags 2*.*), and observed objects not fulfilling the selection criterion for z > 0.5 galaxies (i.e. AGN); TSR =−99 for objects outside the considered area and selection magnitude range (i.e. either i < 17.5 or i > 22.5). |
| ssr | Spectroscopic sampling rate as described in Sect. 6.3. SSR is =−1 for stars (z = 0.0000), non measured objects (flag 0), low confidence redshift measurements (flags 1.*), spectroscopic BLAGN (flags 1*.*), serendipitous targets (flags = 2*.*), and high redshift galaxies (zspec > 3); SSR =−99 for objects outside the considered area and selection magnitude range (i.e. either i < 17.5 or i > 22.5). |
