If the parameters are set to use add noise to the data, the program will then do this. At the end of the routine, the evennoise.pro program will print the moments of the resulting signal to noise. The first entry is the mean and the second is the variance. Additionally, the program will print a plot of the new signal to noise values. The graph should be smooth to within the tolerence set in the parameters file.
Any gaps are the locations of rejected spectra.
The data cube will be cyclically processed. The screen updates the coordinates of the row which is being processed and lists the locations of rejected spectra. This is the longest part of the routine, timewise. It's good to do something else during this period. Once complete, the SCF algorithm saves its results to a file entitled 'scf.data' which is in the IDL save format.
