Class AduHorizontalFit

  util.CommandLineParser
      astro.AduHorizontalFit

public class AduHorizontalFit
extends CommandLineParser

Takes a (multi-extension) fits file and reads it horizontal line per horizontal line. For each line a polynomial fit up to the specified order is calculated, i.e. we start with a straight line (=polynomial of first order) up to Σ_n a_n*x^n. The RMS of the fit is calculated and print to std-out. A second command line argument specifies a width (>1) of the scan line (i.e. the fit is then done to the average ADU), a third does specify an extension to read.
