Notes. Columns are: ESO survey ID, observation date, considered observation mode (IRDIS, IFS or both simultaneously), spectral band: broad band (BB) or dual band (DB), number Nframes of selected temporal frames, total amount of field rotation ∆par of the field of view, individual exposure time DIT, total exposure time TDIT, DIMM coherence time τ0, average seeing, and the first paper reporting analysis of the same data. All the observations are performed with the apodized Lyot coronagraph (APLC; Carbillet et al. 2011) of the VLT/SPHERE instrument. Both seeing and coherence time come from SPARTA estimations except for the observations of 2014 and 2016 where ESO’s Astronomical Site Monitor estimations were used. The central wavelengths of the J, H, H2, H3, K1 and K2 filters are λ = 1.245, 1.625, 1.593, 1.667, 2.110, and 2.251 µm respectively. The IRDIS epoch in boldface is used in Sect. 4.4 as a reference dataset to build nine semi-synthetic epochs.
