Description

I found a potential discrepancy in the code:

Line F[7,3] = -ve^2 / r_earth^2 should be changed to F[7,3] = -ve / r_earth^2.

This matches Equation (40) from the thesis "Aerial Simultaneous Localization and Mapping Using Earth's Magnetic Anomaly Field".

and Equation (5.21) from the thesis "Advanced Aeromagnetic Compensation Models for Airborne Magnetic Anomaly Navigation"

Could you confirm if ve was accidentally squared here?

Research direction

Locate the get_pinson function and inspect the assignment to F[7,3]. Compare the ve term with Equations (40) and (5.21) linked in the issue. Done means confirming whether ve is incorrectly squared and updating the expression if the discrepancy is verified.
