Ephemeris solution

Orbit quality

time +0 +6 +12 +18 +24
σ (α) 0.018 0.017 0.020 0.019 0.023
σ (δ) 0.015 0.015 0.016 0.016 0.018

Time is number of months after last observation (2017-07-31) and σ are in arcsec.

Residuals (O-C) with NIMA ephemeris


z scale (in colour) is the weight in arcsec used in the fitting process
