In this SOC Guaranteed Time proposal we will follow-up on several
(11) galaxies detected with ISOCAM in the Lonsdale et al filler
survey, and which have good reshifts optained from follow-up
groundbased work.  These sources have z=0.2 to 0.7 and represent
a very high redshift sample of luminous infrared galaxies.
We will determine accurately the SED in the ISOCAM filter range and
will additionally sample the long wavelength region of the SED
at 90 and 160 um.
