Yes. Worse than usual. Not sure why. Obvious during heading change/acceleration PROCESSOR : T.

[X] There WERE some gaps! One gap right at beginning of cruise. I'm just going to delete that data. 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) Number of edited points: 40 out of 42 amp = 1.0039 + 0.0017 (t - 86.9) phase = -0.06 + 0.0796 (t - 86.9) median mean std amplitude 1.0040 1.0039 0.0073 phase -0.0715 -0.0568 0.5027 nav - pc 1.0000 0.8250 1.8521 var 0.0010 0.0007 0.0007 min var 0.0000 0.0004 0.0006 delta-u -0.7600 -0.2830 2.3650 delta-v -1.0100 -0.2680 3.9026 Good enough to do edits first. (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) Minor edits - cut out the beginning with the gap. I feel like there's more of an underway bias than usual. Obvious changes in current direction with acceration and heading changes. Not sure why it seems worse than usual. (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: 40 out of 41 amp = 1.0041 + 0.0018 (t - 86.9) phase = -0.06 + 0.0854 (t - 86.9) median mean std amplitude 1.0045 1.0041 0.0078 phase -0.0735 -0.0618 0.5049 nav - pc 1.0000 0.7750 1.9413 var 0.0010 0.0008 0.0007 min var 0.0000 0.0004 0.0006 delta-u -0.7600 -0.2832 2.3656 delta-v -1.0100 -0.2695 3.9032 Small tweak and we're good. Looks pretty pretty nice. (5) apply calibration correct to third sig fig for amplitude; second for phase if both are positive values, enter a positive correction quick_adcp.py --steps2rerun rotate:apply_edit:navsteps:calib --rotate_amplitude 1.0041 --rotate_angle -0.06 --auto Number of edited points: 40 out of 41 amp = 1.0001 + 0.0019 (t - 86.9) phase = -0.01 + 0.0821 (t - 86.9) median mean std amplitude 1.0005 1.0001 0.0078 phase -0.0135 -0.0079 0.4942 nav - pc 1.0000 0.4250 1.5834 var 0.0010 0.0006 0.0006 min var 0.0000 0.0004 0.0006 delta-u -0.5650 -0.2535 2.3623 delta-v -1.0100 -0.2613 3.8942 (6) web plots: quick_web.py --interactive cd ../ cat wh300/cruise_info.txt dm_notes_wh300.txt > wh300.txt ALL done
