Reports the current state of the Sherpa session
show_all([id, outfile=None, clobber=False])
The show_all() command returns information about the current Sherpa session. This includes source and background data and response files that have been loaded, the current statistic and optimization method, and models that have been defined. The current parameter values for the models are included, as well as information on the most recent fit. Model values and fit statistics are updated each time a new fit is run.
- id - the id of the dataset to use; default is to show information for all available datasets.
- outfile - name of the file in which to store the information
- clobber - a Boolean switch which indicates whether or not the 'outfile' should be overwritten, if the file already exists; default=False
The behavior of the screen output is determined by the user's $PAGER environment variable setting, which is usually a variant of "more." To disable paging within show_all() - i.e. print the entire contents, even if it scrolls offscreen - change this setting to "cat" before starting Sherpa:
unix% setenv PAGER cat unix% sherpa
Print the current state of the Sherpa session. This session has spectral data with ARF and RMF loaded. The model parameter values reflect the most recent fit.
