Bugs

  1. modelflux values are incorrect in CIAO 4.2 Sherpa v2.

    The modelflux tool in Sherpa v2 of CIAO 4.2, released in July 2010, currently returns fluxes and count rates in the incorrect units of counts s-2, photon cm-2 s-2, or ergs cm-2 s-2. modelflux in Sherpa v1 of CIAO 4.2 is unaffected by this bug and returns reliable model flux values.

    Workaround:

    To work around this bug, multiply the flux and count rate values by the exposure time, to calculate the correct values in the correct units.
