File structure:
The files list the source time and location for a vibe sweep stack followed by the travel time
 to each nodal instrument and two means of pick quality assessment.

[Year] [Month] [Day] [Hour] [Min] [Sec] [Lat] [Lon] [Depth_km] [UTM_E] [UTM_N] [Elev_m] [VibePoint]
[Stage] [Node] [Time_sec] [SNR] [RMSD]

Auto-pick method:
The p-wave arrival picks were generated from a Akaike information criterion (AIC) algorithm. A
 window was set for the pick based on predicted travel times generated from a preliminary
 inversion. The window was +/- 0.1 seconds from the predicted travel time. If no pick was
 generated within the window at a nodal station, no pick is listed.
RMSD is determined from comparing the AIC output to an idealized curve created by stacking the
 results of several confident picks.

Timing and Location:
The auto-picker was run on a stack of three to six sweeps. The location was the same for every
 sweep in the stack. There may be a variation in location between stages, but by no more than
 a few meters. The timing of the second P-mode sweep was used as the timing info for the stack.
