Hi Doug, Analytic signal and related peaks location are depending of inclination and declination of Earth's Magnetic Field, so the AS procedure may involve a first RTP calculation but only in the case this transformation results stable.
I suggest you to read the very helpful paper by Xiong LI Li X. 2006. Understanding 3D analytic signal amplitude. Geophysics 71(2): L13-L16.
