Missed 5 scans, probably because of longer slew times.

Very bad weather for K-band affected the beginning and several periods of the 48h observation (afternoon storms both days). |

June 3rd, UT 18:44-18:50, we found that the connection between the
antenna control system and the fluxbuff recorder was lost, but after
investigating the recorded data, it seems that the recording itself was
okay. But there could be some impacts on the data recorded during this
period and we remark the issue here. |

About 20 scans were missed because the keyword value AX1LIM was
incorrect in the NRAO Sched station data file and the 20-m antenna
failed to get the proper wrap/unwrap commands from the SNAP file. The
incorrect keyward value did not affect our astro-VLBI observations
until our antenn control system has recently started to support
wrap/unwrap function. |

Looks like noise diode had failed; hence antab file useless. No other known problems. |
