Paul,

The experiment started a little late due to pulsar checks with
the spigot.
The first good observation started at 06:46 UT.

The GBT pointing schedule was modified at the last minute
to turn the phase cals and noise cals off for the pulsar and
on for the calibrators.  Apparently there was a problem
with the modified file, with the consequences that

all observations of the calibrator J0209+6437
were missed during the following times:

06:49 to 07:51
10:28 to 11:44
14:21 to 15:38
