Aquascat Data Loader is updated with the Loader of Guillaume Froment (with Dexmes data). Save as and Open actions are added and connected to create_table_for_save_as.py and read_table_for_open.py. Data are saved in sqlite database. Four tables are created : File (acoustic_data (integer) and acoustic file), Measure (acoustic_data, frequencies, kt, nb_profiles, nb_cells and other measurement information), Settings (temperature, tmin, tmax, depth_min, depth_max) and BS_data (backscatter data with time, depth (list of 2D arrays) and BS_raw_data (list of 3D arrays)). 3D arrays are saved with binary (np.tobytes()) in one cell of table BS_data (BLOB type). They are then loaded with np.frombuffer() function.

The acoustic data tab has been updated, and the variables in the settings python file have been modified: all are python lists, allowing you to work with multiple acoustic data. Each list are filled with object with as many object as there are acoutic data. 1/ File list widget is added to add/clear/delete buttons. Measurement information is displayed in a scrolling text box. Table of backscatter values is added. Limits of dataset in display option box are displayed with double slider. Limits of dataset are displayed in Display options box with double sliders. Double sliders are also used for river bottom detection.

Aquascat data are adapted to UBSediFlow data. The 3D array backscatter acoustic signal is reshaped into frequency shape * depth shape * time shape. Depth and time arrays are transformed into 2D arrays: each line corresponds to a frequency. As the Aquascat data have the same depth and time values for all frequencies, we simply repeat the same line.
