Ephemeris solution
- Observations used : MPC (1988-2017) + OPD (2011,2013,2014) + ESO (2013-2014,GaiaDR2)+ Cerro Tololo (2014) + Occ (2013.06.03,GaiaDR2) + Occ (2014.02.16,GaiaDR2) + Occ (2014.03.16,GaiaDR2) + Occ (2014.04.29,GaiaDR2) + Occ (2014.06.28,GaiaDR2) + THA (2015.03,GaiaDR1) + Occ (2014.04.26,GaiaDR2) + ESO (2015.05) + Occ (2015.05.12,GaiaDR2) + SOAR (2015.07) + ESO (2016.04,GaiaDR1) + SHOC (2016.04.12, offset) + OPD (2016.04) + ESO (2016.06,GaiaDR1) + OPD (2016.07,GaiaDR1) + Occ (2016.07.25,GaiaDR2) + Occ (2016.08.10a,GaiaDR2) + Occ (2016.08.15,GaiaDR2) + Occ (2016.10.01,GaiaDR2) + Occ (2017.02.08, GaiaDR2) + Occ (2017.04.09, GaiaDR2) + OPD (2017.05, GaiaDR1) + Occ (2017.06.22, GaiaDR2+PM) + Occ (2017.07.23, GaiaDR2+PM)
- Observations not used : OPD (2013.08.03) because of bad O-C + Occ (2015.05.12) from MPC (doublon) + Occ (2016.08.08) because bad O-C.

Residuals (O-C) with NIMA ephemeris
z scale (in colour) is the weight in arcsec used in the fitting process

Blue bullets are 'offset' observations not reduced with Gaia DR1, light blue are 'offset' observations reduced with Gaia DR1, green bullets are 'offset' observations reduced with Gaia DR2, red bullets are 'occultation' positions, light red bullets are 'occultation' positions reduced with Gaia DR1 and orange bullets are 'occultation' positions reduced with Gaia DR2.
