GilaGeophyLogbook.pdf - scanned logbook.

Geometry:  5cm group spacing.  Shot is 5cm from closest phone.  Shot is 5cm
           off of the line.  Shots alternate between 1.25m hammer and a
           .2m solinoidand alternate ends of the phones.

NMO: Shot in loose sand.  
If v=60, T0=.05s, x=1.25, then Tx = .0541664 (dt or nmo = .0041664)
If v=60, T0=.02s, x=1.25, then Tx = .028 (dt or nmo = .0088)
