Method Detail

main

public static void main(String[] arg)
                 throws nom.tam.fits.FitsException,
                        IOException

First index is the fits file (decompressed), second is the power in x-direction, third the power in y-direction. Thus focus.fits 2 0 returns the second-order moment M_x^2. Added with focus.fits 0 2 this gives the square of A_4, a good proxy for defocus.

Throws:

nom.tam.fits.FitsException

IOException
