Beginning of ReadMe : III/250 The VIMOS VLT deep survey (VVDS-DEEP) (Le Fevre+ 2005) ================================================================================ The VIMOS VLT deep survey. Le Fevre O. et al. <Astron. Astrophys. 439, 845 (2005) > =2005A&A...439..845L ================================================================================ ADC_Keywords: Photometry, UBVRI ; Photometry, infrared; Galaxies, spectra ; Atlases Keywords: cosmology: observations - galaxies: high-redshift - galaxies: distances and redshift - surveys - galaxies: evolution - cosmology: large scale structure of Universe Decsription: This catalog contains the "First Epoch" sample from the VIMOS VLT Deep Survey (VVDS). The VVDS goals, observations, data reduction with the VIPGI pipeline and redshift measurement scheme are discussed in the paper. Data have been obtained with the VIsible Multi Object Spectrograph (VIMOS) on the ESO-VLT UT3, allowing to observe = 600 slits simultaneously at a spectral resolution R= 230. A total of 11564 objects have been observed in the VVDS-02h and VVDS-CDFS "Deep" fields over a total area of 0.61deg2, selected solely on the basis of apparent magnitude 17.5<=I(AB)<=24. The VVDS efficiently covers the redshift range 0<z<=5, successfully going through the "redshift desert" 1.5<z<2.2, while the range 2.2<z<2.7 remains of difficult access because of the VVDS wavelength coverage. A total of 9677 galaxies have a redshift measurement, 836 objects are stars, 90 objects are AGN, and a redshift could not be measured for 961 objects. There are 1065 galaxies with a measured redshift z>=1.4. When considering only the primary spectroscopic targets, the survey reaches a redshift measurement completeness of 78% overall (93% including less reliable objects), with a spatial sampling of the population of galaxies of  25% and  30% in the VVDS-02h and VVDS-CDFS respectively. The redshift accuracy measured from repeated observations with VIMOS and comparison to other surveys is  276km/s. From this sample we are able to present for the first time the redshift distribution of a magnitude-limited spectroscopic sample down to I(AB)=24.
