ISOPHOT-S AND ISOCAM OBSERVATIONS OF SEYFERT GALAXIES: THE CfA SAMPLE openParPART IIclosePar

scientific abstract we propose to study the 2.5 to 12 micron spectrum of about 80% of the sources in the 46 active galaxies cfa sample with phots in chopping mode and isocam with lw filters no. 2(5.08.5 mu) and no. 7 (8.510.7 mu). the remaining sources are either too faint (no iras detection at 12 micron) or the subject of a different observing cp program. to the cfa agn.s, we have added a set of about 20 bright seyfert galaxies. the cam broad band images are necessary to understand the spatial distribution of the flux and how it may affect the energy distribution observed with phts. the cfa sample is a well controlled and complete hard xray selected sample of seyfert i and seyfert ii galaxies in sbout equal proportions. hence, the phots spectra and isocam images will constitute an ideal database for statistical studies. our main scientific goals are the following: (i) disentangle the various emission components thermal and nonthermal which contribute to the observed near and midir flux (ii) search for spectral features characteristics of dust (iii) search for broad (>3000 km/s) spectral lines in seyfert ii galaxies which are thought to be obscured seyfert is, and (iv) search for molecular bands as tracers of the putative molecular torus which is postulated to surround the core of agns. this programme is complementary to that by rodriguez espinosa and collaborators who plan to use phtp and phtc to study a similar sample . because the list of aot is longer than 99, the proposal has been split into two. this is the second part of the proposal. observation summary all sources are observed both with phts and cam in single pointing mode. the phot aot used is pht40 in chopping mode. with isocam, we use aot cam01 with lw broad band filters no. 2 (5.08.5 micron) and no. 7(8.510.7 microns) at a pixel magnification of 1.5 arcsec. exposure times truncated!, Please [truncated!, Please see actual data for full text]
