How do we get real sensor noise distribution?

[lesialin]

For the initial background noise histogram "init_bgn_hist_cpp("../../data/noise_pos_161lux.npy", "../../data/noise_pos_161lux.npy")"
there are noise distribution for 161 lux and 3k lux.
How do we get our own noise distribution file for our event sensor, so that we can generate the simulated events for specific event sensor?? Thanks
