New to ASTAP photometry. I got my lightcurve plotted in Excel but the (now dated?) YouTube wasn't quite matching what I was seeing with the today's downloaded version.
I loaded files that were platesolved and calibrated elsewhere (so no ASTAP CALSTAT or whatever keyword in the header). There was no "Refresh astrometric solutions" button in the Photometry tab which apparently forces one to use Manual star selection and no "Annotate variables" button. (Screenshot attached) Is there a way to obtain that functionality? -Jesse
Hi Jesse,
In the last weeks there have been major changes in the interface. The documentation update is outstanding.
1) The refresh astrometry is in the popup menu. See attached.
2) The photmetry tab has three modes. See also marked asttached image. It is either a)manual marking or b) measure all annotated or c) meausre all. If you use option b) measure all annotated you can select the to report stars in the REPORT window after pressing the report button.
Cheers, Han
The menu option "refresh astrometric solutions" is one step above the marked menu.
I just figured the Refresh, though I still can't get anything annotated to show (so Measure all annotated don't do nuthin').
Also if I open the set in Inspector and Analyse, I thought there was a way of copying things over to Photometry. But I can't figure that. So I open again in Photometry and when I Analyse over there there's no HFD, Stars or Lim-magnitude.
Between tab options, left click dropdowns, checked and highlighting, it's all somewhat confusing.
"Measure all annotated" is a mode. After selecting "measure all annotated " you have to press the play button indicated with the >|
Just stay at the photometry tab. "Inspector and Analyse" is something else and not related to photometry.
I be doing that and nothing's happening. The scrolling log says detected 0 stars and added 0 annotations yet it's drawing boxes around... something?
The limiting mangitude selected is 11. See red marked attachment. First download and install the database down to 13 or 15 magnitude
https://sourceforge.net/projects/astap-program/files/star_databases/variable_star_database.exe/download
Select then down to magnitude 13 or 15. Alternatively you could also select the online version of the annotation database down to magnitude 99.

Still getting 0s (attached). Thanks for your patience on this. It's past midnight here and I'm still sober, so I'll check in tomorrow :)
Attach tomorrow one of you images so I can have a look.
I have solve astrometrically solved you first screenshot. The field of view is about 031 x0.21 degrees (based on the screenshot) and there are no AAVSO variables or reference star for this small field.
You can still measure using the manual mode. Select a) "Manaully star selection" and in the viewer click on the variable star and check star you want to measure. The press play and you table will be filled with magnitudes. Press the report button to create a report, select in the report window 1) the variable, 2) check mark Gaia ensemble and 3) Select the check star.

Thanks. I'd already done the manual mode (close to what you described) and was wondering how I could get the fancy annotated stars I saw in the YouTube demo. When I finished the manual run I saw three fancy star names for the target, reference and check I selected (though I don't remember any involvement with a Gaia ensemble).
I was thinking you were using something with more coverage than your AAVSO source for references. I think their APASS DR10 has pretty good coverage. Impressive solving the screenshot! The actual FOV of each image is almost half a degree. -Jesse
