Standard-star Archive
This directory contains my official photometry for named primary and secondary standards as of certain benchmark dates. In the case of Landolt (primary) standard stars, these photometric indices represent the weighted average of Landolt's results with my own. In the case of secondary standards, the results are mine alone.
- Column 1: Star name
- Column 2: estimated intrinsic variability in magnitudes rms
- Columns 3-12: magnitude, error in V, B, I, R, U (historical reasons, don't ask)
- Columns 13-17: number of observations obtained on photometric occasions in V, B, I, R, U; (assuming Landolt's are all photometric)
- Columns 18-22: total number of observations in V, B, I, R, U
Don't trust the U too much.
