thaw (and rthaw)

allow fixed parameters to vary

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):

Syntax: rthaw [<param range>...]

where <param range> =:: [<source number>:]<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.
