Summary

• Upgrades for ANISE 0.4.3: https://github.com/nyx-space/anise/releases/tag/0.4.3

Improvements in the computation of eclipsing lead to significant improvements of the solar radiation pressure modeling when compared to GMAT:

Error accumulated in full sunlight over 24 days : 0.488737 m 	0.000081 m/s
test mission_design::force_models::srp_earth_full_vis ... ok

Error accumulated in ecc+inc MEO (with penumbras) over 24 days : 1.866381 m 	0.000635 m/s

Error accumulated in circular equatorial LEO (with penumbras) over 24 days : 5.989316 m 	0.006456 m/s
test mission_design::force_models::srp_earth_leo ... ok

Note that some of these changes could be due to the improvements in the ephemeris itself by using ANISE in the first place, but I don't think so because I'm pretty sure I had checked that.

Architectural Changes

• EclipseState is gone
• line_of_sight and eclipse_state are both removed in favor of ANISE's implementation
• Ruggiero "max eclipse" initialization now takes a penumbra percentage instead of an EclipseState
