Mid-infrared spectra between 5 and 17 mm towards several Class 0 sources as
observed with ISOCAM. All of them show
strong ices and silicates absorption. The three spectral windows are indicated by arrows in
the VLA1 panel. The data for L1448-C,
L1448-N, Cep E and IRAS2 have not been analysed as carefully as those of VLA1+VLA2 and VLA4
in HH1-2, and represent a first look to
the infrared emission detected by ISO. These spectra need additional refinements like a fit
of the instrumental point source
function to the data. The astrometry for all the sources is better than 2-3 arcsec and has
been derived from other bright objects
in the observed fields (except for L1448-C which is at the edge of the field of view of
ISOCAM and could have a larger position
uncertainty). The VLA1 fit (continuous line) is obtained from the empirical absorption
derived for VLA4 (continuous line) by
scaling the total visual absorption by a factor 2.
