Signal processing tab is modified. According to the input data choice, the user can loaded a file for noise data and plot SNR field, BS corrected field with SNR criterion and averaged pre-processed signal. A button is added (close to the combobox of data to processed) to update the input data.

Measurements Information group box has been standardized between Aquascat and UBSediflow: the same characteristics are used and value are displayed according to the frequency. Note that the modifications have been made for delete and clear data (but not yet finished).

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.

Names of BS numpy arrays are changed : BS_data and BS_data_section become, respectively, BS_cross_section and BS_stream_bed. In general, name of variables including data under river bottom line is composed with _cross_section. Name of variables with NaN under river bottom line is composed with _stream_bed.

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.
