Brorfelde Schmidt CCD目录（BSCC）
Brorfelde Schmidt CCD Catalog (BSCC)
摘要：
布罗费尔德-施密特CCD星表（BSCC）包含大约1370万颗恒星，位于赤纬+49度以北，具有精确的位置和V，R测光。该星表是根据2000年至2007年期间布罗费尔德施密特望远镜观测到的18，667帧CCD图像的缩减而构建的。Tycho-2星表用于天体测量和光度测量参考星。对于R = 10至18等的恒星，单个位置的误差约为20至200等。与2 MASS和SDSS的外部比较显示，在BSCC中可能存在高达约30 mas的小系统误差。该星表补充了2 MASS星表的J、H和K_s星等。目录数据文件（约550 MB ASCII，压缩）将在斯特拉斯堡数据中心提供。
英文摘要：
The Brorfelde Schmidt CCD Catalog (BSCC) contains about 13.7 million stars, north of +49 deg Declination with precise positions and V, R photometry. The catalog has been constructed from the reductions of 18,667 CCD frames observed with the Brorfelde Schmidt Telescope between 2000 and 2007. The Tycho-2 catalog was used for astrometric and photometric reference stars. Errors of individual positions are about 20 to 200 mas for stars in the R = 10 to 18 mag range. External comparisons with 2MASS and SDSS reveal possible small systematic errors in the BSCC of up to about 30 mas. The catalog is supplemented with J, H, and K_s magnitudes from the 2MASS catalog. The catalog data file (about 550 MB ASCII, compressed) will be made available at the Strasbourg Data Center (CDS).
