VizieR Online Data Catalog: Multicolor photometry of A2255 galaxies (Yuan+, 2003)

The BATC photometric observations of A2255 were taken with the 60/90cm f/3 Schmidt Telescope of BAO, located at the Xinglong site with an altitude of 900m. A Ford 2048x2048 CCD camera was equipped at the prime focus of the telescope. The field of view was ~1.0 square degree, and the spatial scale was 1.7" per pixel. The combined image in each filter covers a sky region of 59x59arcmin², defined by a right ascension range from 17:08:03.7 to 17:16:8.6, and a declination range from +63:36:31.5 to +64:35:28.8 (J2000.0). The BATC filter system includes 15 intermediate-band filters, namely, a-k, m-p, covering the whole optical wavelength range from ~3000 to 10000{AA}. For distinguishing explicitly between the SDSS and BATC filter names, in this paper we refer to the SDSS filters and magnitudes as u', g', r', i', and z', which correspond to central wavelengths of 3560, 4680, 6180, 7500, and 8870{AA}.
