+The purpose of the codes are to convert data output files of GEOPSY (http://www.geopsy.org/) into more practical figures ready for scientific publishing. 
+Enjoy !

 ## 4. HVSR polarisation.py:
 The H/V rotational module in Geopsy computes the azimuth in which the resonance frequency has a maximum amplitude. To facilate reading this polarisation, this python script plots the variation of the amplitude with azimuth in a polar plot. The IDs to plot will be loaded from the HVSR database file. Polarisation data (Amax, Amin and their corresponding azimuths and frequencues) will be exported to a separate file which then can be visualised in a GIS.
