1)Schedule did not start on time; data recorded from scan 14 (UT 2020.050.22:52:00) onwards
2)Initial data recording format was wrong. Corrected to full 8 channels from scan 34 (UT 2020.051.00:26:50) onwards. Prior to this scans 14 to 34 inclusive were recorded with setup from expt v252bt. 4 Chans of data were recorded but do not expect data to be useful(?) as channel assignments were wrong
So, some channels have overlap but none are properly aligned!
Most likely cause of problem was failure to generate proc file when vex drudged. Recording just continued with configuration of previous expt.
