Abstract:
We present accurate UBV(RI)C photometric sequences for an additional
20 symbiotic stars. As for the 20 targets of Paper I (Henden et al.,
2000, Cat. J/A+AS/143/343), the sequences extend over wide
brightness and color ranges, and are suited to cover both quiescence
and outburst phases. The sequences are intended to assist both present
time photometry as well as measurement of photographic plates from
historical archives.
