- sherpa.astro.ui.save_filter(id, filename=None, bkg_id=None, ascii=True, clobber=False)¶
Save the filter array to a file.
ascii (bool, optional) – If
Falsethen the data is written as a FITS format binary table. The default is
True. The exact format of the output file depends on the I/O library in use (Crates or AstroPy).
clobber (bool, optional) – If
None, then this flag controls whether an existing file can be overwritten (
True) or if it raises an exception (
False, the default setting).
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
filenameparameter. If given two un-named arguments, then they are interpreted as the
filenameparameters, respectively. The remaining parameters are expected to be given as named arguments.
The output file contains the columns
Write the filter from the default data set as an ASCII file:
Write the filter for data set ‘src’ to a FITS format file:
>>> save_filter('src', 'filter.fits', ascii=False)
