Thaw model parameters so they vary during a fit
The thaw command thaws the specified model parameters so that they may
vary during a fit.
-
parameter(s) - model parameters to thaw
To fix a parameter at the current value during a fit, use the freeze
command
("ahelp freeze").
Thaw the amplitude parameter of a powerlaw1d model named "pl".
sherpa> set_source(xswabs.gal*xsmekal.mek)
sherpa> thaw(mek.kT)
Create a source model and thaw the plasma temperature parameter (kt)
of the xsmekal model.
sherpa> thaw(poly.c1, poly.c2)
Thaw the second and third (c1, c2) coefficients of a polynomial model.
