Jessica,
here some responses to your question I forward from grav/mag expert Dr. Neda Bundalo:

1)The book that contains the RTP formula and FORTRAN code:
R. Blakely: Potential Theory in Gravity and Magnetic Applications (check it on Google Books.)

2) GX's (executable) that can be used within OasisMontaj Viewer
http://pubs.usgs.gov/of/2007/1355/ - README and installation for the  GX's

Hi there,

 

Would anyone know of a practical equation for the reduction to magnetic pole (to apply directly to TMI data)? Or maybe software package capable of performing the calculation?

 

Perhaps it goes without saying, but the aim is to apply the equation to raw TMI data so as to obtain magnetic values which are more representative of the magnitude and physical location of the causative bodies.

 

Any information or references would be appreciated!
