 * `n_raw_bins`: Number of bins for pixel raw values in histograms. Defaults to n_charge_bins if not specified.
 * `raw_histo_range`: Axis range for pixel raw values axes in histograms. Defaults to charge_histo_range if not specified.
 * `correlations`: If `true`, correlation plots between all (before and after applying cuts) tracks and all clusters on the DUT (i.e. associated + non-associated) are created. Defaults to `false`.
-* `inpixel_bin_size`: The bin size for inpixel plots. Defaults to `500 nm`
+* `inpixel_bin_size`: The bin size for inpixel plots. Different bin sizes can be set for the x and y axis. Defaults to `0.5um`, `0.5um`.
