SHIP NAME       : Knorr 
CRUISE :    A20 (kn173a)
DATES :     2003/09/15 to 2003/10/13
PORTS :     WHOI to Port of Spain,Trinidad
CHIEF SCIENTIST :John Toole
DB_NAME :        onstation_underway/a173a
PINGDATA :       LTA files
STATUS :     ready for JASADCP
COMMENTS :   Ocean Surveyor 75KHz with a bad ringing problem.  Only
         on station data were acceptable on this leg.  Heading corrections
         were done with Ashtech data.

(0) setup:

adcptree.py kn173a /home/ulili/programs lta
cd kn173/ping
 \ls -tr  /mnt/firewire/data_archive/osdata/knorr075/kn173a/vmdas_data/*LTA > filelist
linkvm.prl filelist
cd ..

(1) load
due to ringing: have to move the reference layer deeper

 quick_adcp.py --dbname a173a --yearbase 2003 --no_head_corr \
--rl_startbin 4 --rl_endbin 20 \
--use_smoothr  --datatype oslta --datafile_glob "*LTA"

(3) edit now; before rotating


(4) rotate, check calib

see cal/rotate/fix_gyro.m; includes
- converting ENS file headings to gyro/*hdg.rbin
- converting N2R files to ashtech/*.adu.rbin
- fixing vmdas timestamps (bad utc conversions)
- runing mk_gyrodh.m

now rotate using "rotate rotate1.tmp" (gyrodh.ang)
and check calibration:
