Micro Tremor SPAC results

Post by rcoulsey »

We have been trying to calculate dispersion values for a passive array, but the values that are being output from Geopsy to the .target file seem to be just a little wrong. The curves generated seem to show a reasonable behavior if the values are assumed as velocity even when they re slowness, but then they are off by 1 or two orders of magnitude. If we make them velocity the behavior is entirely wrong, but the 6-10hz band has reasonable values. Is there any way we can focus our SPAC procesing to output more of these 'reasonable bands' for use? Following are the graphs from spac2disp.
