If the soundsource does not have applied values, the measured soundspeed will be used in the TOA edit window.

Added first version of the new backward tracking method. It is now possible to use interpolation methods as well.

Integrated the empiric_offset and empiric_drift parameter of the float, Changed copy offsets layout.

The measured soundspeed is now being updated on applying a status to temperature and pressure, as well as on loading an rfb file.

The user now gets notified when there are points selected that do not match the lifetime of a soundsource.

The restore view button has been implemented in a custom function for temperature, pressure and toa window.

Pick point and polygon methods are now equal to time of arrival in pressure and temperature windows.

Improvements to the selection modes in edit time of arrival window. The ginput method is not used anymore.

Bugfix, the launch position TOA is now being returned as separate parameter to not disturb the program.
