Comparison of the sensitivities of the NaCo-LP (Vigan et al. 2017; dashed red lines) and SHINE (this work; solid black lines) surveys (with the current sample), based on the average probability of detecting a companion as a function of its mass and semimajor axis. The analysis is based on detection limits that were converted using the COND-2003 evolutionary tracks for both surveys. The contours for the NaCo-LP are not labeled but are the same as for SHINE, and correspond to equal levels of detection probability. The range of semimajor axes spanning the H₂ O and CO snow lines for the stars in the sample are overplotted (see Sect. 2.6 for details).
