= 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:
