Undistored track markers using Python API

Hi everyone,

I wrote a script to export tracking data (for a physics lab course). I access the marker coordinates using

yellowxy=[bpy.data.movieclips[0].tracking.tracks[2].markers[idx].co.xy for idx in range(90)]

which works. However, the markers that I get this way are not undistorted. Does anyone know if there is a way to get at the undistorted marker coordinates. Thx!
