Dear Colleagues,

I have compiled a event list of the IRTS attitude operation. This list
was made using the latest orbit information (to determine the timing
of point-D), and includes the effect of the delay of timer commands.

Each columns shows the following.

1st column      Planned date (UT)
2nd column      Planned time (UT)
3rd column      The difference (s) beween the planned time and the really
                carried out time. Most of the attitude operation was
                carried out using timer commands. Hence there were some
                difference between the planned time and the really
                executed time. The exception is the 2nd raw; this
                operation was carried out using time-line commands, hence
                this is the MC-time.
4th column      g-angle (degree)
5th column      roll-offset (degree, so-called Hshizume's phai)
6th column      SFU spin rate offset from the nominal value (0.0638 deg/s)
7th column      ESA BIAS angle (degree)

Please let me know any errors.


Best Regards,
