M BUG 05/31/19 2264 When plotting models with just one additive group, PlotDirector should not be making redundant calls to makeSourceComponents(). Or if it does, makeSourceComponents should know not to recalculate anything. This is slowing things down considerably when plotting complicated single additive group models. M ENH 09/06/19 2276 Integrate PyXspec's MCMC output with corner.py. M BUG 09/13/19 2277 Fakeit will seg-fault when run on a spectrum with a diagrsp. (Andy Beardmore) M BUG 11/25/19 2285 For a spectrum with multiple models and a non-zero systematic model error, check that square of the sum of models is being handled properly (see 9/6 "Pearson Chisq fix" email). M BUG 05/15/20 2301 When the goodness commands is not run from a valid fit state, if an exception propogates to the top, it will run a fit to restore things to the fit state, not necessarily the original state. M ENH 02/18/21 2326 Possible speed improvements can be made to Apec's opening/reading of data files. See 2/17 email. (Jeremy Sanders) M ENH 05/25/21 2338 Maintain 2 Xspec.init template files, one for Mac and one for Linux. Then have the Makefile copy the appropriate one to user's Xspec.init based on the HD_HOST setting. This way the default HTML browser variable can be set appropriately without the user having to do it. M BUG 01/12/22 2358 When making 1-D contour plots, user-defined values for the placement of contour levels are not being applied. (Julia Ahlvind) M ENH 02/04/22 2363 For ignore/notice commands, allow user to explicitly give the desired units. Example: xspec.AllData.ignore("**-7. 35.-** angstrom"). This is partly to avoid the ambiguity of integers vs. floats determining whether to use channel numbers or energy/wavelengths. M ENH 02/14/22 2365 In CCfits, provide a way to retrieve a bool Keyword into a string arg. We currently can do this for doubles, floats, and ints, but not bools. (Andrew Consiglio) M BUG 02/23/22 2367 "save all" should save "energies" command information.
