(2) linked Leg2 with Leg2_A using link_uhdaslegs.py (3) ran adcp_database_maker.py to make os75nb os75bb using the following dxdy correction xducer_dx -5 xducer_dy 6 (4) check accurate heading device (POSMV): - look at figures in cal/rotate *hcorr.png for gaps (gaps would be red "+" signs -- there are none) figview.py cal/rotate/*png conclude: corrections required at the following ddays - [102.9, 106.3] (4.5) ran patch_hcorr.py to fill missing heading data points (5) check calibration: (a) look at heading correction: are there gaps? does it need to be patched? (b) look at watertrack and bottom track calibrations: what can we expect? (a) catwt.py ADCP watertrack calibration Number of edited points: 152 out of 152 amp = 1.0029 + 0.0002 (t - 118.1) phase = -0.09 + -0.0122 (t - 118.1) median mean std median mean std amplitude 1.0030 1.0030 0.0084 <--- no scale factor phase -0.0570 -0.0985 0.5394 <--- phase adjustment needed (-0.06) ===> look at the watertrack figures: figview.py cal/watertrk/*png (b) cal/botmtrk/btcaluv.out (no bottom track) conclude: no action needed (6) Edit out any bad points or profiles, or the data below the bottom using dataviewer.py -e (7) Recalculate the calibrations quick_adcp.py --steps2rerun rotate:apply_edit:navsteps:calib --rotate_angle -0.06 --auto catwt.py Number of edited points: 150 out of 152 amp = 1.0030 + 0.0002 (t - 118.1) phase = -0.04 + -0.0129 (t - 118.1) median mean std amplitude 1.0030 1.0030 0.0084 <--- within 0.3% of one phase 0.0010 -0.0414 0.5387 <--- within 0.05deg of zero (8) use of 'uvship' algorithm cleans up a dozen profiles or so.
