Module functions to instantiate new source or instrument models.
Integer_Type create_model(String_Type[,String_Type])
Integer_Type create_inst_model(String_Type[,String_Type])
Success/Error Return Values: 1/0
Arguments:
(1) Name of Sherpa model component (e.g., GAUSS)
(2) ID applied to that component (e.g., g)
See the related Sherpa command
CREATE for more information.
NOTE: In CIAO 3.1 the definition of INSTRUMENT BACK is required for fitting
PHA data if either background file or background models have been
defined. INSTRUMENT BACK is set automatically when the PHA data file
is input to Sherpa, however it is deleted if the NEW
background file is input for a given data set. Thus the new INSTRUMENT
BACK has to be defined on the command line before starting a
simultaneous fit with the new background file.
Instantiate a polynomial model, and name it p:
sherpa> () = create_model("POLY","p")
Instantiate an rsp instrument model, and name it a:
sherpa> () = create_inst_model("RSP","a")
Instantiate a Gaussian model with default ID:
sherpa> () = create_model("GAUSS1D")
sherpa> SHOW
