ADC_Keywords: Clusters, galaxy ; Galaxies, photometry ; Photometry, CCD Keywords: galaxies: clusters - galaxies: elliptical and lenticular, cD - galaxies: fundamental parameters - galaxies: photometry - galaxies: distances and redshifts - cosmology: large-scale structure of Universe Abstract: In this paper, we present a set of photometric observations in 15 colors of stars in the Landolt SA95 field with the BATC (Beijing-Arizona-Taipei-Connecticut) system. The wavelengths covered by the system range from 300nm to 1000nm. Visual magnitudes of the stars studied in the field are from the 10th to 20th mag. The observational methodology and the data reduction procedures are described. The relationships between the BATC intermediate-band system and the Landolt UBVRI broad band system are obtained. A catalogue of the photometry has been produced which contains the spectral energy distributions (SEDs) of 3613 stars. File Summary:

Note (1): The value of 00.00 means that there is no measurement because the star is too bright and saturated in this filter band. The magnitude error of these stars is estimated to be 0.03.

Note (1): The center is at 03:54:16.88 +00:19:08.1. The symbols are: b: (saturated) bright star, the coordinates may not be correct. d: Affected by environment (The ghost of the image, bad pixel, etc.) e: The position of the star is near edge of the image. f: The star is very faint but visible. g: galaxies m: May be mixed with nearby star n: Difficult to see star in the image s: Affected by nearby saturated bright stars t: Affected by nearby galaxies x: Not sure to be a real star Note (2): For some faint stars, the magnitude of aperture photometry are used instead of PSF fitting. A "X" indicates that the magnitude is obtained by aperture photometry and has been corrected to PSF magnitude.
