TSYS, LATE |
Nearly linear clock rate of ~0.5 usec / day. Clock offset is 41.593 usec at start and 41.0723usec at end. Obs started without problems, but we noticed that the OCTAD bit distribution was broken before UT 01:30 (Scan #32). It was fixed from UT 01:40 (halfway through Scan #33). Rain during the second half of the observation. |
