Undoes background subtraction.
sherpa> UNSUBTRACT [<dataset range> | ALLSETS]
where <dataset range> = #, or more generally #:#,#:#,..., such that #
specifies a dataset number, and #:# represents an inclusive range of
datasets; one may specify multiple inclusive ranges by separating them
with commas. The default dataset is dataset 1.
The UNSUBTRACT restores the input source dataset
amplitudes to the Sherpa session.
See the documentation on the
SUBTRACT command for more details and
an example.
