Here are meta-data of the Shapiro steps are stored as csv-files These are the data we get when evaluating the absorption images, see paper. The csv files are organized as follows Experimental data Keys: vel, | delta_z | N | I_m | f | Velocity in mm/s | Delta z | Atom number | Modulation current as I_m/I_c | Modulation Frequency in Hz | To proceed with the data use the get_meas_data function. Simulation data keys I/I_c | chem_pot | I_m | Normalized Current | Chemical potential difference in Hz | Modulation current as I_m/I_c |
