- sherpa.astro.ui.save_image(id, filename=None, ascii=False, clobber=False)
Save the pixel values of a 2D data set to a file.
ascii (bool, optional) – If
Falsethen the data is written as a FITS format binary table. The default is
False. 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).
sherpa.utils.err.IOErr – If
filenamealready exists and
False. If the data set does not contain 2D data.
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.
Write the pixel values to the file “img.fits”:
Write the data from the data set ‘jet’ to the file “jet.img”:
>>> save_image('jet', 'jet.img', clobber=True)
