[] There WERE some gaps! Did NOT run patch_hcorr.py. (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 Number of edited points: 37 out of 41 amp = 1.0058 + -0.0013 (t - 190.8) phase = -0.01 + 0.0929 (t - 190.8) median mean std amplitude 1.0030 1.0058 0.0090 phase -0.0210 -0.0120 0.4537 nav - pc 0.0000 0.4054 1.6238 var 0.0010 0.0006 0.0006 min var 0.0000 0.0003 0.0005 delta-u -0.6500 0.1595 3.6689 delta-v -0.1200 0.2930 3.4534 quick_adcp.py --steps2rerun rotate:apply_edit:navsteps:calib --rotate_amplitude 1.0058 --rotate_angle -0.01 --auto Number of edited points: 38 out of 42 amp = 1.0002 + -0.0014 (t - 190.8) phase = -0.01 + 0.1021 (t - 190.8) median mean std amplitude 0.9990 1.0002 0.0087 phase 0.0155 -0.0086 0.4594 nav - pc 0.0000 0.2105 1.5796 var 0.0000 0.0004 0.0006 min var 0.0000 0.0004 0.0006 delta-u -0.5750 0.2621 3.6519 delta-v -0.0800 0.2253 3.3407 Looks decent. (3) edit: gautoedit.py from gautoedit, for every screen do - mark seabed if necessary - additional manual editing if necessary - apply edits (creates/appends new a*.asc files with new flags) (4) apply editing quick_adcp.py --steps2rerun apply_edit:navsteps:calib --proc_engine python --datatype uhdas --auto (if you don't want to sit and hit y for all questions, add "yes | " before the command (no quotes)) Number of edited points: 38 out of 41 amp = 1.0002 + -0.0014 (t - 190.8) phase = -0.01 + 0.1021 (t - 190.8) median mean std amplitude 0.9990 1.0002 0.0087 phase 0.0155 -0.0086 0.4594 nav - pc 0.0000 0.2105 1.5796 var 0.0000 0.0004 0.0006 min var 0.0000 0.0004 0.0006 delta-u -0.5750 0.2621 3.6519 delta-v -0.0800 0.2253 3.3407 Good enough. Mean and median phase are split. (5) apply calibration correct to third sig fig for amplitude; second for phase if both are positive values, enter a positive correction No further correction needed.
