S2001-107-1

S2001-107-1

Astrometric observations of S2001-107-1 centered on (107) Camilla.
Dot represents one observed position. The vector shows ephemeris position from observed position.

S2016-107-1

S2016-107-1

Astrometric observations of S2016-107-1 centered on (107) Camilla.
Dot represents one observed position. The vector shows ephemeris position from observed position.

All components on the tangent plane

Propagation of the solutions
We use all orbits from 1,2 and 3 sigma issued from Genetical algorithm, and we see where the satellite is for the occultation date. North on top, and East on right.
  • Center at coordinates 0,0 is Primary
  • Black dots show the orbit with the best solution at the date of occultation
  • Green zone show orbits covering 1-sigma error
  • Blue zone for 2-sigma
  • Red zone for 3-sigma

S2001-107-1
This figure represent 194736 orbits computed to the occultation date. Each orbit is classify throw its performance, given an accuracy in kilometer :
  • 1-σ error = 71 km
  • 2-σ error = 73 km
  • 3-σ error = 76 km

S2016-107-1

S2016-107-1
This figure represent 194736 orbits computed to the occultation date. Each orbit is classify throw its performance, given an accuracy in kilometer :
  • 1-σ error = 969 km
  • 2-σ error = 1020 km
  • 3-σ error = 1020 km
