Magnetic field direction derived from the methanol maser Zeeman splitting observations presented in this paper projected onto the Galactic plane. The symbols are the observed star forming region with kinematic distances from Pestalozzi et al. (2005) unless better distances were available. The open circles and crosses indicate a clockwise and counterclockwisemagnetic field direction respectively. The approximate location of the spiral arms is indicated as taken from Taylor & Cordes (1993).
