Synopsis

Module function to set the units for 1-D spectral analysis.

Syntax

Integer_Type set_analysis([Integer_Type],String_Type)

Success/Error Return Values: 1/0

Arguments:

(1) Dataset number (default 1)

Description

The set_analysis() function tells Sherpa the units in which to do subsequent analyses, for the specified dataset.

sherpa> instrument = rsp[a](example.rmf,example.arf)
sherpa> () = set_analysis(1,"hz")
sherpa> get_analysis()
