I think I found the problem. The voigt.vtherm parameter goes negative during the fits (because I allowed for a minimum value < 0 in set_par). I think it wasn't obvious because fit_counts would crash before updating the vtherm parameter when it went negative. Suggest robustifying voigt.vtherm and voigt.fwhm to not halt ISIS if evaluated when negative? Thanks, Rob ---- You received this message because you are subscribed to the isis-users list.
