SynopsisReports the current state of the Sherpa session Syntaxshow_all() DescriptionThe show_all() command returns information about the current Sherpa session. This includes 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, and are updated after a fit. Information on the most recent fit is also reported. 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 Examplesherpa> show_all() 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.
