IFS detection limits achieved during the non-coronagraphic observations of HD 284149 in terms of Δmag (left panel) and minimum companion mass (right panel) vs. separation. The mass limits are evaluated using the COND models by Baraffe et al. (2003) and assuming an age of 35 Myr. The different colours show the limits for the Y, J and H IFS filters respectively. The dashed line shows the limits evaluated using the images processed using the TLOCI method for speckle suppression (Marois et al. 2014), while the solid lines show the ones obtained using the images reduced using the PCA algorithm (Soummer et al. 2012; Amara & Quanz 2012).
