Optical ident. of BATC Sky Survey X-ray sources
Listed in IVOA Registry (Virtual Observatory)
We present optical candidates for 75 X-ray sources in a 1deg^2^ overlapping region with the 1997 medium-deep ROSAT survey by Molthagen et al. (1996, Cat. <J/A+AS/126/509>).
Description
These candidates are selected using the multicolor CCD imaging observations made for the T329 field of the Beijing-Arizona-Taiwan-Connecticut (BATC) Sky Survey, which uses the NAOC 0.6/0.9m Schmidt telescope with 15 intermediate-band filters covering the wavelength range 3360-9745{AA}.
These X-ray sources are relatively faint (CR<<0.2ct/s) and thus are mostly not included in the ROSAT Bright Source Catalogue; they also remain as X-ray sources without optical candidates in a previous identification program carried out by the Hamburg Quasar Survey (1998, <J/A+AS/128/507> and 1999, <J/A+AS/134/483>).
