CB54 – 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. Blue vectors have a better error statistic than the red vectors, since they are based on more than one set of observations. The contour lines represent the ¹²CO(1–0) spectral channel maps obtained with the Five College Radio Astronomy Observatory. The solid contour lines give the blueshifted (south-western), and the dotted contour lines give the redshifted (north-eastern) outflow lobe. Contour levels are spaced at 0.3 K km s^-1 intervals of 1.7 K km s^-1 (blue), and 0.15 K km s^-1 intervals of 0.45 K km s^-1 (red), respectively (from Yun & Clemens 1994, beam size of 48′′; reproduced by permission of the AAS). b) Intensity map overlaid with polarization vectors obtained with SCUBA/JCMT in the sub-mm (Henning et al. 2001, reproduced by permission of the AAS). c) Intensity map overlaid with polarization vectors obtained with IMPOL/GIRT in the optical (Sen et al. 2000).
