[X] There WERE some gaps! (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-305) Number of edited points: 25 out of 26 amp = 0.9986 + 0.0030 (t - 253.3) phase = 0.05 + -0.0225 (t - 253.3) median mean std amplitude 1.0000 0.9986 0.0074 phase 0.0270 0.0548 0.3885 nav - pc 0.0000 0.0400 3.5057 var 0.0010 0.0012 0.0008 min var 0.0010 0.0009 0.0007 delta-u -0.0200 0.3340 3.3131 delta-v -1.8100 -0.9280 4.5844 Phase needs adjustment later. (3) from 'edit' dir: 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 ('cd ../'): quick_adcp.py --steps2rerun apply_edit:navsteps:calib --proc_engine python --datatype uhdas --auto (5) apply calibration quick_adcp.py --steps2rerun rotate:navsteps:calib:matfiles --proc_engine python --rotate_amplitude 1.0000 --rotate_angle 0.055 --datatype uhdas --auto tail -20 cal/watertrk/adcpcal.out ** watertrack ** (HOT-305) Number of edited points: 25 out of 26 amp = 0.9990 + 0.0033 (t - 253.3) phase = -0.13 + 0.0963 (t - 253.3) median mean std amplitude 1.0000 0.9990 0.0100 phase -0.1820 -0.1313 0.3734 nav - pc 2.0000 1.2000 4.4628 var 0.0020 0.0022 0.0014 min var 0.0010 0.0017 0.0011 delta-u -0.0100 0.3356 3.3169 delta-v -1.8300 -0.9308 4.5811 Overtweaked the phase.
