Howie, Let me be careful here in distinguishing between peaks and reflections, where peaks can contain one or more reflection (possibly from multiple phases) and only have a position, intensity and gaussian & cauchy widths and are most important for unindexed patterns, while reflections are tabulated by hkl, with lots of information including Gaussian & Cauchy widths, see https://gsas-ii.readthedocs.io/en/latest/GSASIIobj.html#powderrefl-table. Look at the old manual for GSAS to see how sigma and gamma are defined. I don’t think that has made it to the GSAS-II docs.
There are commands and API commands to export peak lists, but I think you want a reflection list, which can be exported with Export/"Powder Data…" From the API, you might be able to use G2PwdrData.Export() (see https://gsas-ii.readthedocs.io/en/latest/GSASIIscriptable.html#GSASIIscriptable.G2PwdrData.Export) to get what you want (you might have to write your own exporter, using the supplied ones as a template.) The reflection list(s) (by phase) are contained in GSASIIscriptable.G2PwdrData.data[‘Reflection Lists’]<https://gsas-ii.readthedocs.io/en/latest/GSASIIscriptable.html#GSASIIscriptable.G2PwdrData.Export>.

In my case this is a simulated pattern.
