There are no previous observations of the IR polarization of these objects at wavelengths > 10 microns. Our goal is to study the wavelength dependance of the IR polarization in order to; - search for contributions from discrete components to the continuum emission (different nonthermal components, possible thermal emission) - search for systematic differences between QSO and BL Lac properties; - attempt to constrain current models (Xmas tree models, homogeneous versus inhomogeneous jet models) for ther production of the nonthermal continuum. OBSERVATION SUMMARY Our goal is to measure the percentage polarization to an accuracy of +/- 4% at 20 microns with PHT50, at 90 and 160 microns with (two concatenated) PHT51 AOTs and at 12 microns for all targets with CAM06 (using the broad-band LW filter). For each target the AOTs must be concatenated to avoid spurious results from any source variability. All targets have optical or near-IR polarization of > 10% and lfuxes range from 100-400 mJy at 12 microns to 0.3 - 5 Jy beyond 100 microns. Recatangular chopping is assumed for the PHT observations. <=== scientific_justification ===> Time distribution for autumn launch targets: Team top40% second 40% third 40% SOT : 11396 0 0 Time distribution for spring launch targets: Team top40% second 40% third 40% SOT : 16947 0 0 <=== autumn_launch_targets ===> 1,"CAM05",1.0,"N","PKS0429-014",04.34542,-01.45778,1950, 0., 0.,900,2 2,"PHT50",1.0,"N","PKS0429-014",04.34542,-01.45778,1950, 0., 0., 2209,3 3,"PHT51",1.0,"N","PKS0429-014",04.34542,-01.45778,1950, 0., 0., 274,4 4,"PHT51",1.0,"N","PKS0429-014",04.34542,-01.45778,1950, 0., 0., 184,0 5,"CAM05",1.0,"N","BL Lac",22.01083,+42.03356,1950,0., 0.,760,6 6,"PHT50",1.0,"N","BL Lac",22.01083,+42.03356,1950,0., 0.,1185,7 7,"PHT51",1.0,"N","BL Lac",22.01083,+42.03356,1950,0., 0.,210,8 8,"PHT51",1.0,"N","BL Lac",22.01083,+42.03356,1950,0., 0.,120,0 9,"CAM05",1.0,"N","3C279",12.89328,-5.18889,1950,0.,0.,900,10 10,"PHT50",1.0,"N","3C279",12.89328,-5.18889,1950,0.,0.,2209,11 11,"PHT51",1.0,"N","3C279",12.89328,-5.18889,1950,0.,0.,274,12 12,"PHT51",1.0,"N","3C279",12.89328,-5.18889,1950,0.,0.,184,0 13,"CAM05",1.0,"N","3C446",22.38639,-05.20472,1950,0.,0.,900,14 14,"PHT50",1.0,"N","3C446",22.38639,-05.20472,1950,0.,0.,2539,15 15,"PHT51",1.0,"N","3C446",22.38639,-05.20472,1950,0.,0.,210,16 16,"PHT51",1.0,"N","3C446",22.38639,-05.20472,1950,0.,0.,120,0 <=== spring_launch_targets ===> 1,"CAM05",1.0,"N","PKS0420-014",04.34542,-01.45778,1950, 0., 0.,900,2 2,"PHT50",1.0,"N","PKS0420-014",04.34542,-01.45778,1950, 0., 0., 2209,3 3,"PHT51",1.0,"N","PKS0420-014",04.34542,-01.45778,1950, 0., 0., 274,4 4,"PHT51",1.0,"N","PKS0420-014",04.34542,-01.45778,1950, 0., 0., 184,0 5,"CAM05",1.0,"N","BL Lac",22.01083,+42.03356,1950,0., 0.,760,6 6,"PHT50",1.0,"N","BL Lac",22.01083,+42.03356,1950,0., 0.,1185,7 7,"PHT51",1.0,"N","BL Lac",22.01083,+42.03356,1950,0., 0.,210,8 8,"PHT51",1.0,"N","BL Lac",22.01083,+42.03356,1950,0., 0.,120,0 9,"CAM05",1.0,"N","3C279",12.89328,-5.18889,1950,0.,0.,900,10 10,"PHT50",1.0,"N","3C279",12.89328,-5.18889,1950,0.,0.,2209,11 11,"PHT51",1.0,"N","3C279",12.89328,-5.18889,1950,0.,0.,274,12 12,"PHT51",1.0,"N","3C279",12.89328,-5.18889,1950,0.,0.,184,0 13,"CAM05",1.0,"N","3C446",22.38639,-05.20472,1950,0.,0.,900,14 14,"PHT50",1.0,"N","3C446",22.38639,-05.20472,1950,0.,0.,2539,15 15,"PHT51",1.0,"N","3C446",22.38639,-05.20472,1950,0.,0.,210,16 16,"PHT51",1.0,"N","3C446",22.38639,-05.20472,1950,0.,0.,120,0 17,"CAM05",1.0,"N","PKS0735+178",07.58722,+17.81917,1950,0.,0.,900,18 18,"PHT50",1.0,"N","PKS0735+178",07.58722,+17.81917,1950,0.,0.,4257,19 19,"PHT51",1.0,"N","PKS0735+178",07.58722,+17.81917,1950,0.,0.,210,20 20,"PHT51",1.0,"N","PKS0735+178",07.58722,+17.81917,1950,0.,0.,184,0
