Supplementary southern standards for UBV(RI)C photometry

Abstract

We present UBV(RI)_C photometry for 80 southern red and blue stars for use as additional standards. The data are tied to the Johnson UBV and Cousins (RI)_C systems and extend the range of the available stars for colour equation determination, especially in (U−B) for blue stars and (V−R) and (V−I) for red stars. Comparisons with published data are made and particularly good agreement is found with Bessell for the red (Gliese) stars.
