... $M_\star \sim 1.2 \times 10^{12} / \mu \mbox{$M_{\odot}$ }$

For the value L_K/M=3.2 adopted for SCUBA galaxies (cf. Borys et al. 2005) one obtains $M_\star \sim 7.8 \times 10^{11} / \mu \mbox{$M_{\odot}$ }$ .

... $1.3 \times 10^{12} / \mu \mbox{$M_{\odot}$ }$

A lower mass $M_\star=2.4 \times \times 10^{11} / \mu \mbox{$M_{\odot}$ }$ is obtained using Eq. (1) and L_K/M=3.2.

Using the s04gyr (Maraston) templates we find best fits at $z_{\rm fit}$ = 2.3 (2.1) and (0.7) 1.3 for #13 and 14 respectively.

Note that our models assume a Miller-Scalo IMF from 0.1 to 125 $M_{\odot}$ , whereas Yan et al. (2004) adopt a Chabrier (2003) IMF.
