The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.
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.
