Function: Converts a multispec format 2D image spectra to an ASCII text spectra. Syntax: ms2ascii msimage asciiname Parameters:
All output files (ASCII text spectra) are called by the root name followed by _ symbol and the number corresponding to the fiber. This number must correspond to the aperture. If you have extracted the apertures with the parameter order=decreasing in the case of bundles SB1 and SB3, you have to put invert = yes. And invert = no in the case of SB2 (for which the parameter order=increasing).
