Notes. When more than one paper reports on the astrometry for a given data set, the values listed in the table refer to the latest astrometric measurement published in the literature. The positions and the associated error bars, the observation dates and the corresponding references can be easily retrieved using PyAstrOFit, through the command PyAstrOFit.Planet_data.get_planet_data(“hr8799b”), for example. The list of all available planets in PyAstrOFit can be obtained through the command PyAstrOFit.Planet_data.which_planet().
The epoch reported in Pueyo et al. (2015) has been discarded from our orbital fitting, see Sect. 4.2 for details.
