(a) CO radial brightness distribution for the naturally weighted map, showing the brightness for each radial bin out to a radius of 95^{﹩\arcsec﹩} (corrected for inclination). For the conversion factor used in this paper, Jy beam⁻¹ km s⁻¹ translates to gas surface density. (b) Intensity cut along the M1 and M2 arms. The resolution has been smoothed to 10^{﹩\arcsec﹩}.
