Top: distribution of . The blue dashed line at 30° indicates themean position angle (θ_fil) of NGC 6334. The red solid line at 130° shows the mean derived fromPlanck data (at the resolution of 5′) toward the field observed with BISTRO (cf., Fig. 5). Bottom: distribution of the polarization fraction PF. The solid and dashed blue lines indicate the mean and median values of PF at 14′′, respectively. The solid red line shows the mean PF^p value derived from Planck data at 5′ resolution toward the BISTRO field.
