Bugs

  1. WCS coordinates returned by Sherpa's get_axes() routine do not match those calculated by the dmcoords tool.

Bugs

  1. WCS coordinates returned by Sherpa's get_axes() routine do not match those calculated by the dmcoords tool.

    The values returned by dmcoords are correct. Sherpa calculates the correct values for fitting (it gets the sign right for the counts amplitude), but is bad for sanity checking or for use beyond Sherpa fitting.
