Here is a list of variables I've attempted to observe in the PMDO images & data.
I am still going through the last few variable star Name Lists, and I keep finding more targets
to add. Meanwhile, I've split this list into two parts:
Target Variables (period >5 days) and
Short Period Variables (period <5 days).
The short period ones are listed only because they may show up at different brightnesses on
different plates, but with one data point per night, no real study of them is possible.
This list is sorted by Right Ascension.
391 Rows found.
About the columns:
- ID: I give stars from each survey I work with a unique ID. Since I'm in the middle of adding
a ton of new targets, these numbers are a mess right now.
- GSC: usually the Guide Star Catalog (1.2) identifier; may also have a USNO A2.0 (U2) or
USNO B1.0 (UB) identifier here.
- Red mag: the red magnitude. I've found that the PMDO camera's color response is
similar to the USNO A2.0 red magnitudes, so these are given here.
- Data: this is a ranking of the types and quality of data I've found.
It is in 3 parts: Image/Curve/PCurve, where:
- Image: If I have tried to get a time-series image, I rate its quality here (A to F)
- Curve: If I have tried to graph a light curve from PMDO data, I rate its quality here (A to F)
- PCurve: If Steve has a light curve on the PMDO website, I rate its quality here (A to F),
or N for stars not on his list yet
Now, the curve ratings are subjective, but here's my guideline:
- A = good density of points, at least one full cycle clearly shown
- B = good density of points, most of a cycle shown
- B- = most of a cycle shown, needs more points
- C = a scatter with a suggestion of variation
- D = too few points
- F = no data at all - this can happen if the GSC entry is listed as a non-star, or for other reasons
