Catalog of Photoelectric Photometry Charts

Update: November 8, 2008

The AAVSO no longer maintains archives of static charts. We now generate custom charts using the new AAVSO Chart Plotting program "VSP"

At this time, VSP does not have built-in functionality to generate PEP-specific charts with labeled check and comparison stars. Because of this we are retaining a link to the old, out of date PEP charts. Please do not use the magnitudes on these charts for your own reductions, and make sure you double-check the SAO numbers for all stars when using a go-to telescope.

The archival page may be found here:

For your convenience, a table showing the SAO numbers for all variables, comparison and check stars in the AAVSO PEP program may be found here:
