Few corrections have been made on calibration, in particular, for the interpolation of the fine sediments profile. The user can invert several acoustic recording with a single calibration. There remains a prolem to display the plots, in particular, when the user switches from one to another acoustic data.

FCB computatuion and display are added on sediment calibration tab. By default, the position of the FCB vertical profile is set on the profile position of calibration samples. The user can choose the depth limits to fit the FCB profile with linear regression. The FCB profile is diplay on acoustic recording 2D field.

Inversion is added to AcouSed. The inversion tab is organised in two part. At the top, fine SSC 2D field is plotted. At the bottom, sand SSC 2D field is plotted. A combobox and a push button are insert on a line at the top. The user choose the acoustic data by clicking on the combobox and run the inversion computation by clicking on the button.

First, the user needs to choise the acoustic file and one frequency. The he can download the fine sediment file and the sand sediment file. For the moment, the two files must have the same number of sample. Concentration and PSD plots are updated with checking sample checkboxes. However, the z/h plot need to be modified.

The parameter kt is divided in two parameter kt_read and kt_modified. In the measurement information groupbox, if checkbox is unchecked, spinbox is disabled and value is kt_read. If checkbox is checked, spinbox is enabled and value is kt_modified, and can be changed.

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.
