[] 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: 23 out of 24 amp = 1.0032 + 0.0006 (t - 212.2) phase = -0.06 + -0.0290 (t - 212.2) median mean std amplitude 1.0040 1.0032 0.0044 phase -0.0250 -0.0619 0.4185 nav - pc 1.0000 0.1739 2.6909 var 0.0010 0.0010 0.0012 min var 0.0010 0.0010 0.0013 delta-u 0.6200 0.0509 3.9114 delta-v -0.0600 -0.0861 3.5179 No tweaks necessary yet.
