If the source has sufficient counts it should be rebinned to allow
the gaussian statistics used in fitting software to be applied correctly.
An example using the GRPPHA program could be:
> grppha myagn_src.ds myagn_src_grp.ds
GRPPHA[] group min 20
GRPPHA[] exit
...... exiting, changes written to file : myagn_src_grp.ds
** grppha 2.9.0 completed successfully
