00016   Normal method:
00017 
00018   does the wavelength calibration and the fitting of the slitlet edge 
00019   positions (ASCII file 32 x 2 values) if wished
00020   produces an array of the bcoefs and of the fit parameters if wished and a 
00021   wavelength calibration map input is an emission line frame and a line list
00022 
00023   o searching for lines by cross correlation with a line list
00024   o Gaussian fitting of emission lines in each column->positions of the lines->
00025     resulting fit parameters can be stored in an ASCII file
00026   o Fitting of a polynomial to the line positions for each column
00027   o Smoothing: fitting of each polynomial coefficient by another polynomial
00028     across the whole frame -> resulting polynomial coefficients can be stored 
00029     in an ASCII file.
00030   o Wavelength calibration map (micron value for each frame pixel) can be
00031     produced by using these coefficients and a cross correlation to the
00032     original frame
00033 
00034   o The slitlet edge positions can be fitted:
00035     1) Automatically (not really stable) or by using guess edge positions
00036     2) By using a Boltzmann or a linear slope function
00037 
00038 
00039   Slit method:
00040 
00041   does the wavelength calibration and the fitting of the slitlet edge 
00042   positions (ASCII file 32 x 2 values) if wished produces a list of the fit 
00043   parameters and of the smoothed coefficients if wished and a wavelength 
00044   calibration map input is an emission line frame and a line list
00045 
00046   o Does the same as other method but smoothes the found polynomial 
00047     coefficients within each slitlet and not over the whole frame.
00048 
00049   o Produces always a wavelength calibration map and does not crosscorrelate.
