(2) scale factor original scale factor 1 additional scale factor (none): 1.003 (3) ADCP (dx=starboard, dy=fwd) meters from GPS original: xducer_dx xducer_dy correction 0 0 final offset 0 0 COMMENTS : Data below the bottom was removed, as well as small bits of data at the the bottom of the sonars range was removed. A strong scattering layer was present and data was removed at the editor's discretion. Editing and updating the dxdy correction improved the data during heading changes.

Check edited, calibrated dataset against original dataset ------------------------------------------------------------------------------ ### Run this: (Has this corrected the problems in the original?) dataviewer.py -c . ../ec150cw.orig ### Run this to compare this sonar with another sonar (after both are finished) dataviewer.py -c ../ec150fw . ### Final cleanup: Because this is a new instrument, we did not realize ### the original depths were too deep by one bin. A specialized program ### was used to correct this ("depth_change_ec"). A log of this change ### is appended to the end of this file. ------------------------------------------------------------------------------ ### 5.
