docs: Return the time delay from the given to detector for a signal with
          the given sky location; i.e. return `t1 - t2` where `t1` is the
          arrival time in this detector and `t2` is the arrival time in the
          other detector. Note that this would return the same value as
          `time_delay_from_earth_center` if `other_detector` was geocentric.
  
          Parameters
          ----------
          other_detector : detector.Detector
              A detector instance.
          right_ascension : float
              The right ascension (in rad) of the signal.
          declination : float
              The declination (in rad) of the signal.
          t_gps : float
              The GPS time (in s) of the signal.
  
          Returns
          -------
          float
              The arrival time difference between the detectors.
