No known issues, but two possibly relevant notes: - Before this experiment, the PPS-counter (gps-fmout) unit was replaced. The signals are the same, so it should not change anything. But if there is a systematic change, this may be the reason. - Before this experiment, it was discovered that (for some time) the LO has been unstable on 5-min timescales, due to ageing. This should have been accounted for in phase-cal, so should not be a problem for past experiments. But, for astro-VLBI phase-referencing without pcal it is a problem. Therefore, the LO was changed to a different (stable) unit. This is a temporary change, until a permanent new LO unit is delivered. This temporary setup should not affect observations, but I note it anyway. Pointing, sensitivity, auto-correlation pcal spectra all look good. So, no known issues.
