Falkor cruises have a small number of edited watertrack points due to procedures. In this case we use a nearby cruise with sufficient points as a measure of whether the calibration is good or not. In this case FK200308 is used, with the statistics: **watertrack** ------------ Number of edited points: 22 out of 37 amp = 0.9998 + -0.0000 (t - 83.0) phase = -0.11 + 0.0098 (t - 83.0) median mean std amplitude 1.0020 0.9998 0.0087 phase -0.0960 -0.1090 0.2784 ------------ As the median amplitude and phase for this cruise do not need correction, we will not apply a correction to the current cruise.

Check heading correction $ plot_nav.py nav/a_fk.gps $ figview.py We have missing heading fixes. $ dataviewer.py $ catwt **watertrack** ------------ Number of edited points: 2 out of 3 amp = 1.0110 + -0.0207 (t - 22.3) phase = -1.10 + -0.3523 (t - 22.3) median mean std amplitude 1.0110 1.0110 0.0057 phase -1.0980 -1.0980 0.0962 ------------ $ cd cal/rotate $ patch_hcorr.py Patching hcorr looks okay with the interpolation. $ cd ../.. # dataviewer.py -c . ../wh300.orig There's a clear change in the data from the fix. # 2.

Or is it too short a cruise? Due to the lack of points, it's hard to calibrate to start. Heading straight to editing points. # 3. Editing points $ dataviewer.py -e Chopped off presumable data acqusition while in port, false returns beyond the seafloor, and cleaned up the top while on station. $ quick_adcp.py --steps2rerun navsteps:calib --auto $ catwt **watertrack** ------------ Number of edited points: 2 out of 3 amp = 1.0115 + -0.0181 (t - 22.3) phase = -0.56 + 2.3938 (t - 22.3) median mean std amplitude 1.0115 1.0115 0.0049 phase -0.5560 -0.5560 0.6534 ------------ # 4.
