Cumulative sub‐mm counts corrected for lens magnification as listed in Table 1. The results obtained by direct inversion are shown by solid circles, while the ±1 σ bounds to the counts estimated from Monte Carlo simulations are shown by dotted lines. Earlier counts from Barger et al. (1998; B98), Eales et al. (1999; E98), Holland et al. (1998; H98), Hughes et al. (1998; Hu98), and Smail et al. (1997; S97) are shown by crosses. P(D) signifies the result of Hughes et al.'s confusion analysis.
