Corrected mass function (number of candidates with |v_⊥| < 2 km s^-1) of the Hyades in the 2MASS K_s band, for regions of various cluster radii: 0 to 3.1 pc (circle); 3.1 to 9 pc (filled square); 9 to 18 pc (triangle); and 18 to 30 pc (open square). The top histogram shows the complete mass function up to 30 pc, fitted with two power laws (thick lines), and a log-normal mass function (dashed line). The Salpeter mass function is shown for comparison (dotted line). The grey areas are the 1-σ locus of the simulation of Ernst et al. (2011) for the cluster centre (r_c < 3 pc, bottom) and the whole volume (r_c < 30 pc, top). The light grey area for m < 0.1 M_⊙ indicates the masses for which our results are strongly affected by incompleteness.
