Allow indicated parameters to vary. (See also freeze).
Syntax: thaw{[ <param range>...]}
where
<param range> =:: [modelName:]<param #> | <param #>-- <param #>
For response parameters (see gain command):
rthaw {[ <param range>...]}
where
<param range> =:: [sourceNum:]<param #> | <param #>-- <param #>
The indicated parameter, or range of parameters, will be marked as variable by the fitting commands and treated as a fitting parameter in subsequent fits. By default, the range will be the last range input by either a freeze or thaw command. See the freeze examples for an example of the use of the thaw command.
