Get Rotation and Scale data from LocRotScale 'Motion Model' track

If I select LocRotScale as the ‘Motion Model’ for a tracker, can I get access to the rotation and scale data after I track an area on some footage?

The data is there since the zoom window shows it stabilized, but I can’t find access to each frame’s rotation and scale data. I have the location coordinates through bpy already.


It looks like the only things available via python are found here:

Is there any other way to get at this data?
