Variation in the projected magnetic field geometry toward the L1172/1174 cloud complex. (a) Optical R-band and Planck polarimetric results overplotted on Herschel column density map. Location of HD 200775 (yellow star) is also shown. The green colored arrows imply the directions of outflow from HD 200775. The eight sectors are indicated using dashed white lines and also marked. Orange lines indicate the polarization measurements in the R band with θ_R ≥ 196° and cyan lines represent the same with θ_R < 196°. White lines represent Planck polarimetric results with 90° rotation. A polarization vector corresponding to 2% is shown for reference. (b) Variation in the θ_R of the sources with respect to the angular separation from HD 200775. Upto 0.4° (Sects. 1–8) there are sources located toward the head region with two sets of distribution of position angles ~211° (red filled circles, shown in orange lines in (a)) and ~179° (blue filled circles, shown in cyan lines in (a)). The green filled circles are the sources distributed toward the tail region. The dashed horizontal line indicates the mean θ_R value (~ 196°) of the same sources. Position angles obtained from Planck observations are shown using thick open black circles (shown in white lines in (a)). (c) Variation in the P_R % and P_P % with respectto the angular separation from HD 200775. The symbols represent the same as described in panel b.
