New with version 1.21 is the BETA version of FORCintense, a graphical implementation of the Muxworthy-Heslop Preisach method of paleointensity determination. For more information about the theory behind this method see the original papers:

A brief practical guide to using the method within FORCinel was presented at  the 2012 EGU meeting in Vienna. The poster can be downloaded here:
