Spacecraft 3-D Normal Point Observations

Observed is based on vector from Earth to planet, both at the same given ephemeris time (ET) where ephemeris time is nominally TDB. Residuals are the observed minus the values from DE 405. Right ascension and Declination observables, residuals, and usigmas are in arcseconds Round-trip light time , residuals, and sigmas are in microseconds.
