LAS\FITS WRITE File[.fits] /MODE SPECTRUM|INDEX [/BITS Nbits]
WRITE the File.fits FITS file from the CLASS Data Format. /MODE is a
mandatory option which can take the following values as argument:
SPECTRUM a simple FITS file is written from the current R spectrum in
memory is written. The number of bits per intensity value
used when writing the FITS file may be controlled through the
/BITS optional argument. It can be: 16 or I*2 (2 bytes inte-
ger), 32 or I*4 (4 bytes integer) or -32 or R*4 (4 bytes re-
al). Default is 32.
INDEX a FITS BINTABLE is written from all the spectra in current
index. The user MUST make sure that all index spectra are
consistent (same source, same line, same frequency setup,
...). The intensity values (and irregularly sampled X axis
values, if any) are always written as 4 bytes real.
The default mode and number of bits can also be specified through the
SET FITS MODE SPECTRUM|INDEX
SET FITS BITS Nbits
The option /CHECK will print the FITS HEADER on the terminal.
