gofio2ascii.py converts the GOFIO ms1d/s1d outputs in ASCII files with or without header
The ms1d file have and 4 column: wavelength (nm), flux, S/N, and number of the echelle order
It is written in python2, but if needed it may be run with python3 by
commenting and un-commenting the appropriate rows:
"lista = raw_input/input ..."
"for o in xrange/range(50):"
The header options are:
- none: no header is written
- simple (default): only two rows with the name of the FITS files and the columns definition
- red: reduced header, with the keywords defined in the "keywords" list
If the user wants different keywords to be saved in the header,
the keywords list may be changed accordingly.
- full: the whole header is written in the ASCII files
Usage:
spa_gofio2ascii.py -h
spa_gofio2ascii.py
spa_gofio2ascii.py [--hea=<value> --split]
spa_gofio2ascii.py <list>
spa_gofio2ascii.py <list> [--hea=<value> --split]
Options:
-h,--help : show this screen
list : list of ms1d FITS data files [Default: fits.lis]
--hea=<value> : write header, options: none/simple/red/full [Default: simple] (defined by the "keywords" list)
--split : split the orders of the ms1d files in different ASCII outputs
