SPHERE/IRDIS images of the HD 112810 debris disk. Each column indicates data processed via a different method: GRAPHIC/PCA (Sect. 4.1; Hagelberg et al. 2016), TLOCI as provided by the SPHERE data center (Sect. 4.2; Delorme et al. 2017) or RDI (Sect. 4.3; Xie et al. 2022); rows indicate each observation epoch. In each case, the two SPHERE/IRDIS channels are co-added. There are no RDI reductions for the BB_H data, since there is far more data collected with the DB_H23 filter in the archive, and the reference library we considered does not collate BB_H data (Xie et al. 2022). The “normalized signal” is calculated relative to the background noise in the wide-field; we note that this is not a true S/N at very small separations, where the noise is higher than the background limit.
