[x] There WERE some gaps! Just one small one at beginning. Data stop after .75 days of cruise. 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: 3 out of 4 amp = 1.0057 + -0.0175 (t - 85.2) phase = 0.06 + -0.5044 (t - 85.2) median mean std amplitude 1.0080 1.0057 0.0049 phase 0.0810 0.0580 0.1271 nav - pc -4.0000 -3.3333 2.0817 var 0.0000 0.0003 0.0006 min var 0.0000 0.0000 0.0000 delta-u -1.4300 0.5367 3.4411 delta-v -3.6100 -1.5933 5.4239 Almost no data present for calibration.
