CB68 – a) DSS-map with overlaid near-IR polarization vectors observed with ISAAC/VLT. The length of the vectors shows the degree of polarization, and the direction gives the position angle. Only vectors with P/σ_P > 3 are plotted. The contour lines represent the ¹²CO(3–2) spectral channel maps obtained with the JCMT. The black contour lines give the blueshifted (south-eastern), the grey, dotted contour lines give the redshifted (north-western) outflow lobe. Contour levels at 0.25,0.50,0.75,... K (from Vallée et al. 2000, HPBW of 14′′; reproduced by permission of the AAS). b.1–3) Same as a) but with polarization vectors obtained with IFOSC/IGO in the optical. c) Intensity map overlaid with polarization vectors obtained with SCUBA/JCMT in the sub-mm (Vallée et al. 2003, reproduced by permission of the AAS).
