FITS READ
LAS\FITS READ File[.fits]
Read the File.fits FITS file to the CLASS Data Format. If the FITS file
has been written (see HELP FITS WRITE) using:
- the SPECTRUM mode, the (unique) spectrum is loaded in the R buffer
(memory only). If needed, you have to open an output file and WRITE it
in order to save it on disk.
- the INDEX mode, the (several) spectra are converted and implicitly
written to the current output file (it must have been opened before).
The previous contents of the Class file is preserved (spectra are ap-
pended).
This command can read 2 flavors of FITS files:
- the CLASS-FITS format (i.e. the one written by FITS WRITE or by some
3rd party softwares). See the CLASS programmer documentation for de-
tails.
- the Herschel-HIFI FITS format. See the dedicated memo for details.
FITS cubes can be converted to the Gildas (not CLASS) Data Format by the
command VECTOR\FITS, and then imported as a Class index by the command
ANALYSE\LMV. See HELP V\FITS and HELP LMV for details.
