PACE89 Shot 46 in SeisWide

Well, I downloaded the PACE 1989 seismic data as two SEGY files yesterday (310 Mbyte) from IRIS.  Back in the 1990s, that was a lot of data.  Seems like nothing now!  I found SeisWide from Dalhouse University and plotted the data from shot 46. Since it's not available at Dalhousie anymore, you can find SeisWide here.  I've not been able to figure out how to plot by true offset.  The traces are equally spaced above.  It converted the standard SEGY to PC SEGY and I bandpass filtered from 2-12 Hz.  I noticed it is reading the offset info from the SEGY trace headers correctly (blue annotation above).  This was done on a PC and is a lot easier than setting it all up on a Linux machine.  Still haven't been able to find a download link for WASPAR, or this one (found it ! PASTEUP download link).

Figured out how to plot the data properly by offset.  Click here for a how-to for SeisWide.
