Start an octave session and type hodo2plot This hodo2plot.m file is different from hodoplot.m in that the components to be plotted are from two different *.seg files, rather than a single *.seg file. An example would be a Rayleigh wave problem where the vertical and radial components reside in different files. 1. prompt for which file is X-axis, which is Y-axis. The code will check that the same number of traces and time sampling are used for both files. 2. GUI, choose a trace to plot. 3. GUI, choose scale factor or just default. 4. GUI, choose a Tmax value, say .05 seconds. 5. GUI, click continue 6. GUI, choose a new Tmax value, say .10 seconds 7. GUI, click continue What you are doing is plotting the particle motion for increasing time steps. KEY POINT: * There will always be a sign convention. Upward velocity produces a negative voltage on vertical phone. Do a tap test for your equipment.
