File support
HTI Physical echo (.bot) file format

File page of the Information dialog box
Warning: The 12kHz sampling rate used to create .smp file cannot accurately sample short pulse lengths. As a result the data in .smp files may not give the true shape of echoes. Both HTI and we strongly recommend that you do not use data from .smp files for target strength estimation. Single target detection variables derived from .smp files may be suitable for fish tracking and fish counting but you will need to view each echogram individually and make this judgment yourself.
Calibration
The documentation explaining how the settings on the Calibration page of the Variable Properties dialog box affect data from HTI echosounders has been improved. See Calibration settings for HTI data.
