(2) see what calibration looks like: amp in [0.995, 1.005] : good enough to proceed to the next step. tweak later phase in (-.5, .5) : good enough to proceed to the next step. tweak later rule of thumb: errors when underway: scale factor of 1.02 (i.e. 2%) gives 10cm/s alongtrack error phase error of 1deg gives 10cm crosstrack error (goal is 1cm/s) tail -20 cal/watertrk/adcpcal.out ** watertrack** (HOT-282) Number of edited points: 21 out of 21 amp = 1.0029 + 0.0003 (t - 68.7) phase = -0.10 + -0.0484 (t - 68.7) median mean std amplitude 1.0030 1.0029 0.0048 phase -0.1550 -0.1034 0.5576 nav - pc 1.0000 1.4762 2.5024 var 0.0020 0.0030 0.0028 min var 0.0020 0.0027 0.0027 delta-u -0.0100 0.1267 3.1142 delta-v -2.9700 -0.8552 4.8578 (sometimes this will need amplitude and phase adjustment in later steps) Looks GOOD (3) edit: gautoedit.py .. from gautoedit, for every screen do - show now - additional manual editing if necessary - list to disk (creates/appends new a*.asc files with new flags) (4) apply editing from dir sonar: quick_adcp.py --steps2rerun apply_edit:navsteps:calib --proc_engine python --datatype uhdas --auto #### NOTE THAT FOR HOT-282 THIS STEP WAS UNNECESSARY ## (5) apply calibration quick_adcp.py --steps2rerun rotate:navsteps:calib:matfiles --proc_engine python --rotate_amplitude 1.000 --rotate_angle -0.000 --datatype uhdas --auto tail -20 cal/watertrk/adcpcal.out ** watertrack ** (HOT-282) Number of edited points: 21 out of 21 amp = 1.0029 + 0.0003 (t - 68.7) phase = -0.10 + -0.0484 (t - 68.7) median mean std amplitude 1.0030 1.0029 0.0048 phase -0.1550 -0.1034 0.5576 nav - pc 1.0000 1.4762 2.5024 var 0.0020 0.0030 0.0028 min var 0.0020 0.0027 0.0027 delta-u -0.0100 0.1267 3.1142 delta-v -2.9700 -0.8552 4.8578 Looks GOOD (remember to save) (6) web plots: mkdir webpy cp ../wh300/webpy/sectinfo.txt webpy/ quick_web.py --redo cd ../ cat os38nb/cruise_info.txt dm_notes_os38nb.txt > os38nb.txt ALL done
