There is a directory of plots for each line with the 3 Borehole Seismometer channels plotted and the location of those shots relative to the borehole. There is also a directory of documentaion for these data. These SEGY files do NOT contain the Latitude and Longitude of the individual shots. These were not perserved from the original data.
