FLAT/FEROS [inspectrum] [flatspectrum] [outspectrum]
17
Remove blaze function from spectrum through division by
18
spectrum of flatfield lamp.
22
Remove blaze function from spectrum through division by
23
spectrum of flatfield lamp.

FLAT/FEROS [inspectrum] [flatspectrum] [outspectrum]
30
inspectrum = root name of input image (extracted spectrum)
33
flatspectrum = root name of flatfield lamp image
36
outspectrum = root name of output image
43
1) inspectrum, flatspectrum and outspectrum are root names.
44
For double fiber mode the names of the files to be
45
accessed are generated from the root name and the appendices
46
1 and 2. For all other modes the filenames are
47
identical with the root names.
49
2) The distinction between single fiber and double fiber is
50
made via the keyword FIBER_MODE.
52
3) flatspectrum must exist on disk. It can be created
53
by applying the command EXTRACT/FEROS to a spectrum
60
Remove the blazefunction using default filenames, which
61
are stored in keywords.
63
FLAT/FEROS thisimage thatimage anotherimage
64
Remove the blazefunction from the spectrum with root
65
name thisimage through division by the spectrum with
66
root name thatimage and store the result in a file
67
with root name anotherimage.
