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. Image credit: Science journal
