Restores settings and/or parameter values.
<arg> may be:
RESET Command Arguments
| none |
Equivalent to RESET MODELS |
| ALL |
Equivalent to issuing RESET MODELS and
RESET METHOD |
| MODELS |
Restores the parameter values of all current model components to their latest
user-defined (or GUESS command-defined) values.
|
| <sherpa_model_stack> [# [ID]] |
Restores the parameter values of all components of the
specified model stack (SOURCE, BACKGROUND,
PILEUP, [B]NOISE, or
KERNEL)
to their latest user-defined (or GUESS command-defined)
values.
# is a dataset number (default 1); see
BACKGROUND for an explanation of ID.
|
| <sherpa_modelname> |
Restores the parameter values of the specified model component to their latest
user-defined (or GUESS command-defined) values.
|
| <modelname> |
Restores the parameter values of the specified model component to their latest
user-defined (or GUESS command-defined) values.
|
| METHOD |
Restores the parameter values of the current optimization method to their
initial default values.
|
| <sherpa_methodname> |
Restores the parameter values of the specified optimization
method to their initial default values.
|
| [B]ERRORS [# [ID]] |
Removes user-defined source or background data error values.
Note that if the errors are not redefined,
then they are subsequently computed using the current choice
of statistic.
# is a dataset number (default 1); see
BERRORS for an explanation of ID.
|
| [B]SYSERRORS [# [ID]] |
Resets the systematic error for every source or background data point to 0.
# is a dataset number (default 1); see
BSYSERRORS for an explanation of ID.
|
| FILTER [#] |
Clears user-defined filters.
# is a dataset number (default 1).
NOTE: the implementation
of this command in CIAO 3.0 contains a bug, such that sometimes the
source and background filters are reset, and sometime only one or the
other; also, there is no RESET BFILTER.
|
| [B]WEIGHTS [# [ID]] |
Resets the statistical weight assignment for every source or
background data point to 1.
Removes user-defined source or background statistic weight settings.
# is a dataset number (default 1); see
READ BWEIGHTS for an explanation of ID.

ERASE
is a related command that may be used
to remove all user inputs and user-defined settings,
or to remove a model component from the current Sherpa session.
Restore the parameter values of the current method to the initial values:
