=>The sky was photometric, so the decision was made to take throughput measure-
=>ments. We obtained one quickly before the UC06 run began.
This was done to check the previous night's thruput observation and
reduction (a check of the accuracy of our measurements).  In general, we
will only be obtaining thruput measurement once per month, generally
during the first week.
