Recovery curves from the artificial core injection experiments. Left: flux recovery fraction, f_flux = F_meas/F_true, as a function of injected true mass, with the corresponding injected 1.3 mm flux density shown on the top axis. Right: number recovery fraction, f_num = N_rec/N_inj. Gray curves show the result for the dendrogram-only method, while blue curves show the dendrogram+Gaussian method. Thin curves show the results for individual ALMA fields, and the thick curves with points show the combined recovery functions weighted by core numbers.
