backscatter_dark_count
(bbp, depth)¶ Calculates an in situ dark count from the backscatter sensor.
The in situ dark count for the backscatter sensor is calculated from the 95th percentile between 200 and 400m.
Parameters: - bbp (numpy.ndarray or pandas.Series) – The total backscatter array after factory calibration in m-1.
- depth (numpy.ndarray or pandas.Series) – The depth array in metres.
Returns: bbp – The total backscatter data corrected for the in situ dark value.
Return type: numpy.ndarray or pandas.Series
