Magnitudes and Intensity Factor Calculator
To convert between magnitudes and brightness or intensity factors (as defined in the
course notes) enter the magnitude you wish to convert to a intensity factor
in the "in" box and then press the appropriate "Convert to Brightness"
button . If you wish to go from a known brightness factor to a magnitude
difference then press the "Convert to Mags" button and the answer
that appears will be the equivalent magnitude difference between the objects.
Remember that the brighter an object is, the smaller its magnitude measure.
