Abstract:
An average of 11 B, V secondary standards per field have been
established for 58 cataclysmic variable stars, most of which are
nova-like variables. The standards are within a few arcminutes of the
variable and are therefore well-suited for CCD photometry. The
standards have brightness of V∼12-17 and have a typical accuracy per
standard of +0.02mag.
