In their survey paper of prestellar cores with SCUBA, Kirk et al. (2005) have
discarded two of our papers on L183 (Pagani et al. 2003, 2004). However these
papers bring two important pieces of information that they cannot ignore.
Namely, the real structure of L183 and the very poor correlation between
submillimeter and far infrared (FIR) dust emission beyond \Avb ā 15
mag. Making the erroneous assumption that it is the same dust that we are
seeing in emission at both 200 and 850 Ī¼m, they derive constant
temperatures which are only approximate, and column densities which are too
low. In fact dust temperatures do decrease inside dark clouds and the FIR
emission is only tracing the outer parts of the dark clouds (Pagani et al.
