Notes. The results from this work are mainly based on the high-quality observations acquired on 2018-06-01 (polarized intensity) and on 2019-07-09 (total intensity), highlighted via (‡). We also successfully detect the disk in the SPHERE/IRDIS total intensity observations of 2016-04-05 and 2016-06-03 (†; see Fig. 2). The other datasets are of poorer quality with for some no (2015-08-01) or almost no (2016-06-13, 2019-06-26) recovery of disk signal. The observation acquired in 2015-04-09 is not exploitable because the focal plane mask was missing during the observation sequence. (α) The 48 exposures correspond to twelve HWP cycles, resulting in a total time on source of Nexp × DIT. GTO stands for Guaranteed Time Observations (PI: Beuzit).
