Caption: Figure A1.
The steps taken to produce the final perihelion and aphelion longitudinal distributions of atmospheric density. Top panels: the perihelion and aphelion distributions using the initial spectral model. Middle panels: the perihelion and aphelion distributions using the updated spectral model. Bottom panels: the perihelion and aphelion distributions with the temporal normalization applied.
