Secondary photometric standards in selected northern dwarf-nova fields

We have compiled a list of secondary photometric standards for 88 northern dwarf nova fields, An average of six stars per field were calibrated through broadband BVR filters, The secondary standards range in brightness from V similar to 11 to V similar to 17, have aB - V color range of similar to 0.1 to -similar to 2.2 and lie within similar to 3' of the dwarf nova. Typical 1 sigma errors are +/-0.05 mag.
