AHELP for CIAO 4.3 Sherpa v1


Context: info


Display the convolved source model


show_model([id, outfile=None, clobber=False] )


The show_model command displays the convolved source model. To obtain the unconvolved model information, use the command show_source ("ahelp show_source").

  • id - the id of the dataset to use; default is to show model 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 command output looks like:

Model: 1
apply_rmf(apply_arf((50000.0 * (xsphabs.abs1 * powlaw1d.p1))))
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   abs1.nh      thawed    0.0349312            0       100000 10^22 atoms / cm^2
   p1.gamma     thawed      1.72895          -10           10
   p1.ref       frozen            1 -3.40282e+38  3.40282e+38
   p1.ampl      thawed  4.24936e-05            0  3.40282e+38

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

Example 1

sherpa> show_model()

Print the model information for all datasets to the screen.

Example 2

sherpa> show_model(2, "sherpa.model", True)

Write the model information for dataset id=2 to the file "sherpa.model", clobbering any existing file with the same name.
