Analyzing profiles

The CLASS user may analyse spectra by fitting profiles. The fitting commands are available from the FIT language. The minimization method is taken from the MINUIT system of CERN, modified and optimized for this purpose. Reliability proved to be good. Five types of profiles are presently available, and can be selected by the METHOD command:

The FIT commands are: Fit results are always saved by a WRITE command and made available through the corresponding variable section (see SET VARIABLE help).
