[] 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 = 1.0019 + 0.0004 (t - 212.2) phase = 0.04 + 0.0036 (t - 212.2) median mean std amplitude 1.0010 1.0019 0.0073 phase -0.0210 0.0364 0.3957 nav - pc 0.0000 0.0435 3.7353 var 0.0010 0.0011 0.0007 min var 0.0010 0.0009 0.0007 delta-u 0.6200 0.1026 3.8526 delta-v -0.0600 -0.0796 3.5167 Continuing with editing.
