     PROGRAM    : uhdas
     PING TYPE  : nb

     PARAMETERS : BT : bottom track mode (on or off)
                  SI : sampling interval or averaging period for ensemble (sec)
                  NB : number of bins
                  BL : bin length (m)
                  TD : transducer depth (m)
                  BK : blanking length (m)
                  HO : heading offset applied by DAS (deg)
                  HB : heading bias (deg)
                  CRPH : compensation for roll-pitch-heading, 1:on, 0:off)

POSITIONS       : gps (specify more detail if available)

CALIBRATION     : original heading alignment: 43.5
                  additional rotation 0
                  final rotation is (original transducer angle) - (rotate_angle)
                                43.5 - (-.86) = 44.35

                  NOTE: not clear why this would be different from leg1

#===========================================

reprocessing from scratch to regain data in regions of low scattering.

# rsync config from the data directory to here;
# modify to have useful paths

(1) # make processing directory

adcptree.py MV1001_os75nb  --datatype uhdas --configbase MV1001 --configpath config

(2) # set up control file

cd $procdir
