DPCC doesn't get RA,DEC from FITS header

[james.lowenthal]

I've got CCD images made with Maxim DL 5.  The FITS headers include OBJCTRA and OBJCTDEC.  
I've input those in AIJ Data Processer > General FITS Header Settings > FITS Header Input Settings.  
Also in the DP window I've put:
Target Coordinate Source = FITS Header target RA/DEC (J2000)
Observatory Location source = Coordinate Converter manual entry.

In the DPCC window, I've indicated Observatory ID = Smith College's McConnell Observatory

But the RA and DEC of the target do not appear in the DPCC's Standard Coordinates section.

This problem propagates through the rest of multi-aperture photometry, and means that in the measurements table, HJD_MOBS=NaN, I guess because it doesn't know where the target is.

How can I get the DPCC to read the RA and DEC of the target properly from the FITS header?

Thanks,
James Lowenthal

Hi James,

It sounds like you have everything set up correctly, but to make sure, could you send me 4 screen shots: (1) The main DP panel, (2) The General FITS Header Settings panel, and (3) The DP Coordinate Converter Panel after you have reduced a couple of exposures (just press Pause if needed), and (4) The aperture settings window (i.e. the one shown below)?

Hi Karen,

Ha!  All working fine now.  Can't explain it.  Sorry to bother you!

We got the problem to show up again.  Different computer, different dataset, but I can't find the different setting that's causing the problem.  We paused the data reduction mid-stream and confirmed that the DPCC *is* getting RA,DEC from the FITS header.  But the output to the measurement results file shows HJD and BJD = NaN, and their column titles (JD_MOBS, HJD_MOBS, BJD_MOBS) are not what we asked for in the Aperture Settings window (HJD_UTC, BJD_TDB).  I have screenshots but can't figure out how to post them to this thread, sorry, have emailed those to you separately.

Thanks,
JL
