Not high quality signals for the range. Gap in first arrivals at sh. 2685. Cannot clearly match up phases on either side. Very jagged topography 2600-2650 obscures much detail PmP2 quite clear Faint pre-crossover PmP seen near sh. 2600 (32 km) Pn-gap not clear but appears to be near sh.2570. This would put cross over at 39-40 km. Closer than most |
