WCOMB N1 N2 N3 WEXP Method -- Combines different telluric standards
Parameters:
N1, N2 -- Range of spectra to combine
N3 -- Output spectrum
WEXP -- Water absorption exponent for scaling of spectra relative
to one another
METHOD -- Rebinning method Linear, Quadratic, Sinc
In some cases you may be able to get good measurements of different regions
of telluric absorption with different stars. You may then want to combine
these into one telluric standard for correcting your objects. WCOMB does
this. Since the different spectra may have been taken at different airmasses
and have different wavelength scales, it has to know the exponent for scaling
the spectra on the basis that the absorption in mags is proportional to the
airmass to the power of WEXP.
