Notes:

This was a second half night with hand over around 11:45 pm MST. 
This was not an originally assigned night, but one that became available in February and
offered to us.


We took 448 images (including calibration).


Note from Dick Joyce:
[…] the barometric pressure sensor at WIYN is misbehaving at times, 
so the resultant precipitable water vapor values will be jumping around.  
Some of the values will be valid (when the barometric pressure values are around 800 mb), 
but some will be way high when the reported barometric pressure drops suddenly.[…] 
Fortunately from ~ 2300 hr to 0500 hr last night there seem to be only two barometric 
pressure values which are a little low, so hopefully that was during the time period 
when you were observing.
