Photometry with MaximDL

MaximDL makes photometry very easy! In a few steps you can determine the magnitudes of your star(s) and even make a lightcurve!

NOTE: Make sure to LABEL all object stars and reference stars. The output .csv file will have multiple columns. Your columns will be labeled Julian date, object star 1, reference star 1, reference star 2 ... and unless you noted which reference star you used you will not be able to reproduce your results in another filter! The Julian date is a fancy way Astronomers keep track of time. The object star and ref star columns will be in magnitude or relative magnitude.
