The standard star spectrum is calibrated and extracted as described for the recipe
vmmosobsstare. The extracted spectrum is compared to catalog fluxes of the same star to
obtain the efficiency curve and the response curve to use for flux calibration. For this
comparison the extracted spectrum is converted into electrons/sec/Angstrom. The catalog
fluxes, as well as the atmospheric extinction factors, are remapped to the same wavelength
bins of the extracted spectrum. After removing the effect of the atmospheric extinction
(i.e., correcting the extracted spectrum to airmass zero), the response curve is derived
as the ratio between the catalog spectrum and the calibrated spectrum.
The efficiency curve is obtained by dividing the extracted spectrum in
electrons/sec/Angstrom by the the catalog fluxes converted from erg/cm/cm/s/Angstrom to
photons/s/Angstrom (at 100% efficiency each photon would correspond to one electron).
