save_pha command fails with fake_pha input
In CIAO 4.4, the Sherpa save_pha command will fail if an attempt is made to write simulated PHA data to file, specifically the output of the fake_pha command.
sherpa> set_source(1, "xsphabs.abs1*xspowerlaw.p1") sherpa> set_par(abs1.nH, val=0.07, frozen=True) sherpa> p1.PhoIndex = 0.8 sherpa> fake_pha(1, "source.arf", "source.rmf", 50000) sherpa> save_pha(1, "simulation1.pha") AttributeError: 'NoneType' object has no attribute 'copy'
The work-around for this bug involves issuing two 'get_data' commands before the save_pha command, as demonstrated below.
sherpa> get_data(1).header = {} # Make header an empty dictionary
sherpa> get_data(1).name = "simulation1.pha" # Update name for save_pha
sherpa> save_pha(1, "simulation1.pha")
This bug will be resolved in a future release of the Sherpa software.
