Module function to retrieve the strings describing filters applied to source and background datasets.
Array_Type get_filter_expr([Integer_Type])
Array_Type get_bfilter_expr([Integer_Type])
Error Return Value: NULL
These functions returns an array of filter expressions,
for use in record-keeping, GUIs, etc.
Each string in this array
is a command that contributed to the calculation of the filter; the commands
were applied to the filter in the order in which they are stored in
the array.
See the related Sherpa command
SHOW ALL.
Retrieve a set of filter expressions applied to dataset 1:
sherpa> fltexpr = get_filter_expr()
sherpa> print(fltexpr)
notice source 1 energy 2 : 4
notice source 1 wavelength 12 : 24
