FIGSEE-Generate a seeing ripple spectrum from a FIGS spectrum

Description:

FIGSEE generates a seeing ripple spectrum from a FIGS spectrum. In principle, the FIGS data can then be divided by this ripple spectrum to take out the effects of variable seeing during the observation.

Parameters:

SPECTRUM

Spectrum to use for seeing data.

NDET

Number of detectors to use.

DETECTORS

Detectors to use.

OUTPUT

Name of resulting seeing ripple data.

 F I G S E E

 Figaro function that attempts to produce a seeing ripple spectrum
 from a Figs spectrum, averaging the data from one or more detectors,
 normalising the result to unity, and generating a spectrum in
 which the normalised data from these detectors (ideally ones not
 contaminated by spectral features) are repeated for each detector.

 Command parameters -

 SPECTRUM    (Character) The name of the file containing the
             spectrum to be used.
 NDET        (Integer) The number of detectros to be used.
 DETECTORS   (Numeric array) The detectors to be used.
 OUTPUT      (Character) The name of the resulting ripple spectrum.

 Command keywords -  None
