2. Deconvolving the Billingsley
-find gains/offsets (minimize difference between |B| and IGRF magnitude along trajectory)
-rotate to principal axis frame (minimize spin-frequency power in axial component)
-use a rigid body rotation model to move between spinning payload frame, and inertial frame
-difference measured B from IGRF B.
-assume differences caused by field-aligned sheet currents:

3. On MICA

4. On RENU2

5. Disbrow attitude

6. Compare mechanics to B

7. Revisit MICA

8. Compare mechanics to B

9. Next steps
--better attitude solution, iterating from magnetic field data and rigid body equations
--rotation of measured B to IGRF frame
--perp components of B and trajectory
--calculation of Jz assuming sheet
--comparison of curlB to divE
--other useful things
