Overview

It produces the nominal scobj, camera orientation and sun vector all in inertial space (J2000). It used to be made by IFRAME.f with the understanding that if it was needed it would be run right after make_sumfiles, but that was confusing and fraught with peril. IFRAME is now used by OMEGA. It lets you get an approximate solution for the transformation from inertial to body-fixed and, if desired, to update the sumfile accordingly. Of course, since there are uncertainties in the nominal values, this isn't quite right, and REGISTER has to be run to align with the current shape model.

IFRAME.TXT is now made by make_sumfiles.

This is all part of the WOBBLE stuff and can be ignored for testing until the procedures settle down. It is being developed and tested with simulated ROSETTA data that has major excited rotational state issues. The procedures appear to be working, but they're a bit ungainly and I'm looking for ways to make the procedure smoother. Laurent and Claire from Marseille will be spending next week with me to beat on just these issues, and Nick, from JPL who is doing shadow nav for ROSETTA will be joining us for a day (he's the first avatar). Note that as long as WOBBLE is not mentioned in INIT_LITHOS, or if WOBBLE=.FALSE. then nothing will change in the testing.
