With the help of China-VO, BATC catalogs are available now at the CDS system, both in FTP categories and VizieR database. It is probably the largest dataset so far that our Chinese astronomers contribute to the international community.
BATC means Beijing-Arizona-Taiwan-Connecticut, which is a multi-color sky survey project conducted in National Astronomical Observatory of China (NAOC). The telescope used by the project is a 60/90cm f/3 Schmidt telescope located at Xinglong Station of NAOC. The filter system includes 15 intermediate band filters, covering a range in optical wavelengths from 300 to 1000 nm. A Ford Aerospace 2048�8 CCD camera with 15 micron pixel size is mounted at the Schmidt focus of the telescope. The field of view of the CCD is 58'*58' with a plate scale of 1.7 arcsec per pixel. From 1995 to 2004, 110 58'x58' sky survey fields have been observed. First release of the BATC catalog includes observation results for 511842 sources located in 70 sky survey fields. The total data amount is about 130MB.
