          Parameters
          ----------
          s0: numpy.ndarray
              Single detector ranking statistic for the first detector.
          s1: numpy.ndarray
              Single detector ranking statistic for the second detector.
          slide: numpy.ndarray
              Array of ints. These represent the multiple of the timeslide
          interval to bring a pair of single detector triggers into coincidence.
          step: float
              The timeslide interval in seconds.
  
          Returns
          -------
          coinc_stat: numpy.ndarray
              An array of the coincident ranking statistic values
