save_table
(id, filename=None, ascii=False, clobber=False)¶ Save a data set to a file as a table.
- Parameters
id (int or str, optional) – The identifier for the data set to use. If not given then the default identifier is used, as returned by get_default_id.
filename (str) – The name of the file to write the data to. The format is determined by the ascii argument.
ascii (bool, optional) – If
False
then the data is written as a FITS format binary table. The default isFalse
. The exact format of the output file depends on the I/O library in use (Crates or AstroPy).clobber (bool, optional) – If outfile is not
None

Notes
The function does not follow the normal Python standards for parameter use, since it is designed for easy interactive use. When called with a single un-named argument, it is taken to be the filename parameter. If given two un-named arguments, then they are interpreted as the id and filename parameters, respectively. The remaining parameters are expected to be given as named arguments.
Examples
Write the data set to the file “table.fits”:
>>> save_table('table.fits')
Write the data from the data set ‘jet’ to the file “jet.dat”, as an ASCII file:
>>> save_table('jet', 'jet.dat', ascii=True, clobber=True)
