Synopsis
Save the data to a file.
Syntax
save_data(id, filename=None, bkg_id=None, ascii=True, clobber=False) id - int or str, optional filename - str bkg_id - int or str, optional ascii - bool, optional clobber - bool, optional
Examples
Example 1
Write the default data set out to the ASCII file 'src.dat':
>>> save_data('src.dat')Example 2
Write the 'rprof' data out to the FITS file 'prof.fits', over-writing it if it already exists:
>>> save_data('rprof', 'prof.fits', clobber=True, ascii=True)PARAMETERS
The parameters for this function are:
| Parameter | Definition |
|---|---|
| id | The identifier for the data set to use. If not given then the default identifier is used, as returned by `get_default_id` . |
| filename | The name of the file to write the array to. The data is written out as an ASCII file. |
| bkg_id | Set if the background should be written out rather than the source (for a PHA data set). |
| ascii | If False then 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 | This flag controls whether an existing file can be overwritten ( True ) or if it raises an exception ( False , the default setting). |
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.
