| Summary:
This page describes the data available for the VIRMOS F22 field. The quantity of the data that has been taken over the years is considerable. This page has recently been updated to include data recently installed on the Terapix disks from tapes. |
| There are several lists of the data available for the the F22 field. Yannick Mellier maintains lists of images on the Terapix web pages. Olivier Le Fevre has a list of images on the VIRMOS web pages. However the only complete list of images is found at the CADC (Canadian Astronomical Data Centre) webpages. Here are the relevant pages: Based information from the CADC, the following 5 figures show the available imaging data in the BVRIZ bands. The outlines (in red) are approximate, based on the image centres from the CADC, rather than actually astrometry of the image. All the images whose centres are closer than 6 arcminutes to each other have been grouped together. The black number in the centre of each band show the total exposure time at that pointing. The centre of the field had been observed to great depth (over 24 hours in the I band for example). |

| The following table list all the exposures of the 22 hour field with exposure times greater than 100 seconds. The CFHT exposure number, the RA and Dec, the filter band, the exposure time, the UTC date are taken from the CADC database. The RunID was taken from the CADC when possible, otherwise it was taken from Olivier LeFevre's webpage or derived from the CFHT observing shedule. There is a note "OLF" if the exposure is listed on the VIRMOS web page and "TPX" if it can found on the Terapix disks. |
