Converting Intensity into magnitudes

  1. Jan 9, 2010 #1
    I need to convert the intensity, 130 counts per pixel into magnitudes per sq arc second. I have been given the radius as 5 arc sec, and a calibration constant, which is 30.8.

    Only you know what the calibration constant and radius represent, so why not explain it to us?
