Known issues: - Something seems strange with the cable-cal values. We cannot get cablediff to work properly (usual cable-cal sign is negative, but turns out positive). Also the values seem smaller than usual. Pcal and all other systems seem to work nicely. Cable-cal issues could be related to summer-maintenance. This is first week after summer maintenance period, so we just got telescope back for observing. Will investigate further after experiment. Data should be useful with manual pcal, if nothing else. ================================ r1959on START ================================= 2020-08-11 17:38:55 r1959, ONSALA60, start message ONSALA60 started R1959 as planned. Known issues as listed in ready message. ================================= r1959on STOP ================================= 2020-08-12 19:04:33 R1959, ONSALA60, Stop message ONSALA60 observed R1959 almost as planned. Known issues: - Cable delay unit behaving strange from start. At 0714 UTC it was rebooted and resumed normal operations. Therefore: A) Pcal and cable cal data before 0714 UTC should be treated with caution. B) There is no "cablediff" sign in the log file, but the sign should be "-" as usual for ONSALA60. ================================= r1959on STOP ================================= 2020-08-12 19:28:59 R1959, ONSALA60, Stop message Correction, as I sent the previous email too soon. One more known issue for ONSALA60 R1959: It seems ONSALA60 was stuck in elevation from ca 1250 UTC, but was unfortunately missed due to remote operations. Surprisingly, the FS recorded the following scans anyway, but likely the telescope was not pointing correctly in elevation after this time.
