Attitude check

This check processes the Attitude History File in order to determine the stability of the attitude reconstruction. odfcheck estimates the stability of the attitude reconstruction by calculating the r.m.s. of the parameters DIFFVRA and DIFFVDEC in the AHF, during the stable pointing period (after the completion of the closed loop slew where VALTIME$>$PTTIME).

If either of the parameters exceeds a user supplied threshold, a warning is issued.
