restore_paramest

Context: sherpa

Synopsis

Module functions to restore the default values of the parameters used to configure each Sherpa parameter estimation method.

Syntax

restore_unc
restore_proj
restore_cov
restore_intunc
restore_intproj
restore_regunc
restore_regproj

Description

These functions restore the default values of the Sherpa configuration variables (also called "state objects") sherpa.unc et al.

To display the current values, use the functions list_unc et al.

See the related Sherpa commands UNCERTAINTY, PROJECTION, COVARIANCE, INTERVAL-UNCERTAINTY, INTERVAL-PROJECTION, REGION-UNCERTAINTY, and REGION-PROJECTION for more information.

Example

Modify the Sherpa state variable sherpa.regproj; display current values with list_regproj; restore the default values:

sherpa> sherpa.regproj.nloop = [30,20]
sherpa> sherpa.regproj.sigma = [1.6,2.6]  # 90 and 95 percent contours
sherpa> list_regproj
