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. from Gaskell email: 14 May 2014 |

IFRAME.TXT
Description
This text file contains the nominal spacecraft to object center vector and camera orientation all in inertial space (J2000) for each picture. IFRAME.TXT is created by the routine make_sumfiles.
In IFRAME.TXT, the SCOBJ vector is in meters. RA, DEC, and TWIST are in degrees. SRA and SDEC are the error in RA and DEC, respectively, in milli-arcseconds.
IFRAME.TXT used to be created by IFRAME.f with the understanding that, if it was needed, it would be run right after make_sumfiles. However, that was confusing and fraught with peril.
IFRAME.TXT 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 you must run REGISTER to align with the current shape model.
Here is a sample IFRAME.TXT file:
