Baseline corrected Delta-B, Geographic, GEO, Spherical, East, North, Up, Coordinates
Finite Differences between adjacent Points on Spacecraft Track were used to determine along Track and across Track Unit Vectors in GEO. No Altitude Change between adjacent Points was assumed. Baseline Correction, F. Rich's MFIT Procedure, is Polynomial Fit every Half-Pass to each Component of Delta-B in Spacecraft Coordinates by using only Data from Regions equatorward of the DMSP Auroral Boundary from the CEDAR Database.
