TWP/C1 - Generator Problem
DataStreams:twpmfrsrC1.a0, twpvceil25kC1.a1, twpsondewnpnC1.a1, twpvceil25kC1.b1, twpmfrsrC1.b1,
twpsondewnpnC1.a0
Description:
On November 18 the generator was turned off due to a fault in the oil
pressure sensor. It had been having trouble for at least a day prior
to the manual shut-down. ADaM, the MPL, and the WSI were also shut
down to prevent an unscheduled power cycle. As a result, there is a block 
of missing data from November 20-27 for all of the instruments except 
those connected to the Zeno loggers (SKYRAD, GNDRAD, SMET).
