cds-question@unistra.frx-ray-sourcessurveysastronomical-object-identificationWe 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>). 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>).2004AJ....127.2579Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/2579CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/262 : BATC Data Release One - BATC DR1 (Zhou+ 1995-2005)J/A+AS/126/509 : HS 47.5/22: X-ray catalogue (Molthagen+ 1997)J/A+AS/128/507 : The Hamburg Quasar Survey.
