*******************************************************************************************************************
UH-CODAS POST-PROCESSED SHIPBOARD ADCP DATA COLLECTED BY THE R/V MIRAI DURING RESEARCH CRUISE CINDY LEG 1.

THE PROCESSING USED SINGLE PING (ENR) DATA, TOGETHER WITH HEADING AND POSITION ANCILLARY DATA.

FOLLOWING STANDARIZED CORRECTIONS TO THE REFORMED VMDAS ADCP DATA, A VISUAL EDITING WAS PERFORMED IN THE ENTIRE DATASET TO FLAG BAD DATA.
 
ALL UH-CODAS SOFTWARE WERE OBTAINED FROM http://currents.soest.hawaii.edu/

Output files (ascii format):

mr1107_sadcp_u.asc (eastward component of velocity)
mr1107_sadcp_v.asc (northward component of velocity)

5 minute average data

Format:

Firt row: 		First column, dummy (set to 0.0), 
			Subsequent columns, depth in meters
Subsequent rows: 	First column, Decimal Day (i.e. 0:00 Jan 1, 2011 = 0)
			Subsequent columns, velocity component (m/s) at depths given in row 1

Absent data set to -99

                  re-check heading correction    [  x  ] <= was required application of timslip_short again as nav/calib steps were redone after first 2 gautoedits

CALIBRATION     : check parameters for original heading alignment
                  additional rotation 0.1 
                  final transducer angle is:
                       (original transducer angle) - (rotate_angle)

COMMENTS        : applied transducer offset: --xducer_dx -7 --xducer_dy 28
		  using os75bb_try01 as modifications (transduce offsets applied at every ping) used on os75bb_try02 did not had any 
effect.
