Dear Colleagues,

I have complied a log of the delay of timer commands.

Some of the IRTS operation, which are wriiten as "<TMR??" in the event
files, were performed using the timer commands. The timing of these
commands are not refered to the absolute time, but are specified to be
executed at some predetermined time after the "Timer Start" command is
executed. The timing of the "Timer Start" command is determined by
the voice operation of the SFU POCC director. Hence it has some uncertainty.

In the following, I compiled a list of "Timer Start" timings. The
first column shows the timing of the "Timer Command" was really
executed, and the second column shows the difference beween the
planned timing and the real timing. The positive value means delay.

Please note that these times are determined by the ground station, and
are free from the errors of the MC-time.

Best Regards,

Takao Nakagawa
