Output parameters

The main sections of the header contain some fundamental parameters which are unique for all the spectrum. This is a problem for the output spectrum from ACCUMULATE or AVERAGE which may contain different part coming from a various number of spectra (e.g. in COMPOSITE mode). Actually, only the INTERSECT mode with SET BAD OR ensures that the same number of input spectra have been used to compute the non-bad channels of the output spectrum.

Nevertheless, typical values have to be given to these parameters. First of all, when adding a new spectrum $obs$ with the previous sum $S_{\ensuremath{\mathrm{in}}}$, the header of the output sum $S_{\ensuremath{\mathrm{out}}}$ is completely copied from $obs$ header. Then specific values of the different sections of the header are adjusted.
