Notes for C.Trees optics data taken from Barber's PP arrays


files 4 and 5, event 02150545 
  Optical sensors were placed at two different depths on the same primary 
production array so each file represents the data collected from a
different depth.


file 8, event 02200305
  contains the data from two deployments over a two day period.


file 9, event 02230320
  contains the measurements from two deployments over a two
day period.  A data gap exists between 2/23 9:49 thru 16:11 hours
and 2/24 5:13 thru 6:02 hours.  Note: the deployment depth is different
on the second deployment.
