Columns are: (1) flux in the 8/24 $\mu$ m data; (2) infrared luminosity; (3) bolometric luminosity; (4) star formation rate; (5) dust attenuation derived from the infrared luminosities; (6) offsets between MIPS catalogue source and LAE candidate in z23 sample; and (7) other remarks. The IDs for the z03 sample are from Deharveng et al. (2008). Full table is available in the online version.
