We present accurate
photometric sequences around 20 symbiotic stars.
The sequences extend over wide brightness and color ranges, and are suited
to cover quiescence as well as outburst phases. The sequences are intended
to assist both present time photometry as well as measurement of
photographic plates from historical archives.
Key words: catalogs -- stars: binaries: symbiotic -- techniques: photometric
