Mean surface density of companions as a function of angular separation for the 22 cores identified in L1495/B213. The red squares represent observed data. The black line and the blue-shaded region represent the mean and the ±rms interval from 100 Monte Carlo simulations of a random distribution of 22 cores. The departure of the red squares from the shaded region at small angles indicates a significant level of clustering at scales less than 700′′.
