How do I change parameter minimum and maximum range limits?
This syntax is described in depth in the Sherpa Reference manual and the paramset ahelp page. In the following example, the user establishes a model component and assigns it a name, then sets a model parameter value and the parameter range limits:
sherpa> pow[modelc] sherpa> modelc.3 = 10.0 sherpa> modelc.3.min = 1.0 sherpa> modelc.3.max = 100.0
The second command, modelc.3 = 10.0, gives the value of 10.0 to parameter number 3 of modelc. The third and fourth commands set the minimum and maximum values for parameter number 3 of the same model component.
