MULTICOLOR BVR CATALOG RELEASED
Maciejewski, G.
July 20, 2004
Recent four month-long observations gathered in BVR bands
allowed us to create the Catalog in BVR - SAVS_BVR. Among
18.400 stars, which were detected on near-V band exposures,
16.000 were also measured in near-R and only 10.700 in near-B.
The catalog contains SAVS designation of observed star, mean
magnitudes in BVR, magnitude errors, number of data points in
every band, equatorial coordinates (J2000), mean epoch of
observation and a name of a field. The sky coverage is illustrated in Figure below.

The full catalog is available in Catalogs section.
To derive transformation of our instrumental magnitudes m_B,
m_V, m_R to the standard BVR system we cross-identified
observed stars with the General Catalog of Photometric Data
and the UBVRIJKLMNH Photoelectric Photometric Catalogue for
BV and R bands, respectively. To find transformation
coefficients for BV equations we used 669 stars with well known
photometry but we found only 69 stars with known R photometry.
The data stored in the BVR Catalog allowed us to plot V-R vs.
B-V color-color diagram for over 10.600 stars. The diagram is
presented in Figure below.
