WebThey are based on Landolt (1992) UBV data for 224 stars in the color range 0.3 < B–V < 1.1 with SDSS ugr photometry from the CASU INT Wide Field Survey. An improvement over previous SDSS – UBVR c I c transformations is the use of two colors in each equation, which is particularly helpful for the u–g transformation.
