Reports the current state of the Sherpa session
show_all(; [id, outfile=NULL, clobber=0]);
The 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, 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=0
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.
