Detection limits at 95% completeness around MWC 758 for the October 2015 (blue line) and the October 2016 (green line) data sets. A false alarm probability of 1% is allowed in our field of view (see Sect. 3.2). The inner region indicated by the gray area is dominated by the presence of the spirals arms. Outward, our detection limits for the October 2015 data set are close to 5 M_Jup, according tothe BT-SETTL evolutionary model (Allard et al. 2012).
