Notes. (a) Algo. refers to the algorithms used for the reduction: smart ADI (sADI; Rameau et al. 2013b), TLOCI (Lafrenière et al. 2007), and ANDROMEDA (ANDR; Mugnier et al. 2009).

The 2018 and 2019 data have not been reported and exploited yet. The 2015, 2016, and 2017 data are reported by Chauvin et al. (2018), but they reduced the data with the IPAG-ADI pipeline; (7) These epochs are not used for the orbital fit of the HD 95086 b exoplanet (see Sect. 3.3).
