Parameters for instrumental response estimation and flux
calibration are displayed by the command:
Midas...> SHOW/LONG f
The flux calibration consists of correcting for atmospheric extinction
using a table 
and of comparing the one-dimensional
reduced spectrum of a standard star 
to a reference flux
table 
. The sequence:
Midas...> SET/LONG FLUXTAB=fei110 EXTAB=atmoexan
Midas...> PLOT/FLUX
Midas...> EXTINCTION/LONG std23 ex23
plots the flux table and corects the one-dimensional reduced
spectrum std23 for the atmospheric extinction. The
instrumental response can be estimated by filtering with the
command:
Midas...> RESPONSE/FILTER ex23
Midas...> PLOT/RESPONSE
or by polynomial or spline interpolation using the sequence:
Midas...> INTEGRATE/LONG ex23
Midas...> RESPONSE/LONG fit=SPLINE
Midas...> PLOT/RESPONSE
The obtained response is stored in the image response.bdf
and can be applied to any reduced, extinction corrected spectrum using the
command:
Midas...> CALIBRATE/FLUX exspec spectrum
