Abstract:
An average of 30 B,V secondary standards per field have been
established for 76 variable stars. These are mostly cataclysmic
variables of various subclasses but also include a variety of other
kinds of variable stars. The standards are within a few arc minutes of
the variable and are therefore well suited for CCD photometry. The
standards have brightnesses of V∼12-17 and have a typical accuracy
per standard of ±0.01mag.
