 17) RT is the semidiagonal of the can (or the interaction vol) and does not depend on the origin position
 18) GPEarth changes the rock radius and not the ocean one in order to have a water layer equal to SiteDepth as suggested by Alfonso Garcia

 9) PEarth calculated taking into accaunt the composition of the Earth layers (Core, Mantle, Rock and SeaWater)
10) Cross section in w2list is the mean cross section along in the neutrino path: PEarth=exp(-Na*XSecMean*ColumnDepth)
