        COMMENTS: (1) Data is transcribed from audio recording made during
                      observation session, with accurate stopwatch set to
                      WWV at start of session.  Times are plus 59 seconds,
                      minus 0 seconds, i.e., times given are *truncated*
                      to the minute.
                  (2) Train length values, when given, are in degrees.
