Synopsis
Erase data and model settings in a Sherpa session
Syntax
clean( )
Description
The clean() function erases all data set IDs and model assignments established in a Sherpa session. This function accepts no arguments.
Example
sherpa> clean()
The clean() function resets a Sherpa session by erasing all user-defined data and model settings.
