What do the Sherpa 'get' commands do?

The 'get' commands simply return the command-specific information that has been written to the user-specified data set ID. For example, the get_analysis command is used to access the current units setting for a PHA data set which has been loaded, as follows:

sherpa> load_pha(3, "3c273.pi")        

sherpa> get_analysis(3)         

This command returns the string 'energy', identifying the units setting for data set 3.
