Caption: Fig. 4.
Plot of simulated rotation measures generated from magnetic field directions deduced from OH Zeeman splitting. No simulated rotation measures are plotted for Galactic longitudes unsampled by the data of Figs. 3 and 4. The dots represent extragalactic rotation measure data as taken from Rand & Kulkarni (1989) at Galactic latitude ﹩b=-15﹩°, 0°, and 15°. See § 5.3 for further details.
