Astro capstone meeting notes:  Jan 25, 2022

Present: Richmond, Dussault, Lertviwatkul

  Nititee shows his light curves

     - has complete data in B and V

     - discussion of good vs. bad data -- which measurements to keep
              and which to discard

     - important: keep copies of BOTH
              all measurements, and graphs using all measurements
              only the good meausurements, and graphs using only good data

     - try to identify the reasons for bad measurements


  Michael shows his light curves

     - V light curve complete, still working on measuring B-band images

     - keep working


  Calibration into magnitudes

     - AIJ provides (star - sky) in INTENSITY units, for both target
               and comparison stars
 
     - we need to convert to MAGNITUDE units, with proper calibration

     - step 1: use Aladin to look up B and V magnitudes of two comparison
               stars.  Note the uncertainties in magnitudes as well

     - step 2: pick one of the comparison stars.  Compute

             mag(var)  =  mag(comp)  -  2.5*log10[ inten(var)/inten(comp) ]

               Do in both B and V bands.

     - step 3: pick the other of the comparison stars.  Again compute

             mag(var)  =  mag(comp)  -  2.5*log10[ inten(var)/inten(comp) ]

     - step 4: compare the two sets of B mags, and two sets of V mags.
               If all went well, they should agree


  Tomorrow (Wed, Jan 26): Nititee shows calibrated light curves
