Bow magnetic morphology from Eq. (5). The magnetic fields are averaged along the LOS. Colored lines represent the modeled x,y, and z components of the magnetic field. The colored symbols represent the x, y, and z components of the observed magnetic field. On x-axis, X is the perpendicular distance from the filament’s long axis, and L is LOS integration distance. Left panel shows best fit for Eq. (5).
