Bugs

vtpdetect with negative coordinates  (16 May 2007)

Running vtpdetect on a level 1 event file may fail with an error that all the events are at the same location and the tool cannot tessellate. This is related to the (normal) bad coordinates at the beginning of the ObsID where there is no aspect data.

Workaround:

If you must work with the evt1.fits file, apply a time filter before running vtpdetect.
