2021-02-18 14:07:04 <a.orlati@ira.inaf.it> R1986 feedback from Noto
Dear colleagues,
we just realised the operator failed to post a proper feedback in the end experiment message(R1986).
Here what it should have been the feedback from Noto:
The readout from weather station was not working so no wx parameters are available
S-band receiver was not properly patched during first couple of hours so this data is not valid and should be discarded.
Please contact us In case further details are needed.
Regards.
Andrea.
