XCSAO Template Flags

These flags are added after the template R-value column on the final summary plot produced by xcsao.
-a
Absorption lines have been removed from object and template spectra.

/c
Continuum has been divided out of the object and template spectra. This happens if DIVCONT = T in the template spectrum header.

-e
Emission lines have been removed from object and template spectra.

-f
The template spectrum was not filtered before the cross-correlation. This flag is set if FI-FLAG in the template spectrum header is set to 1 or 3. It is used if the template spectrum has already been filtered or if emission lines are being cross-correlated.

+h
High frequencies of the object and template spectrum Fourier transforms have not been filtered, only low frequencies. This is set if the FI-FLAG keyword in the template spectrum header has been set to 2 or 3 and If -f is set, too, the template spectrum transform has not been filtered at all.

+tc
Continuum has not been removed from the template spectrum.

+w
The entire wavelength space which is shared by the object and template spectra was used. The wavelength limit parameters in xcsao, st_lambda and end_lambda, were ignored for this template/spectrum pair. For this to happen, the OVERLAP flag in the template spectrum header must be set to T.
