 DC Forward Simulation
 =====================
 
-Forward model conductive spheres in a half-space and plot a pseudo-section
+Forward model two conductive spheres in a half-space and plot a
+pseudo-section. Assumes an infinite line source and measures along the
+center of the spheres.

+INPUT:
+loc     = Location of spheres [[x1,y1,z1],[x2,y2,z2]]
+radi    = Radius of spheres [r1,r2]
+param   = Conductivity of background and two spheres [m0,m1,m2]
+stype   = survey type "pdp" (pole dipole) or "dpdp" (dipole dipole)
+dtype   = Data type "appr" (app res) | "appc" (app cond) | "volt" (potential)
