Scientific paper

Results are presented of mapping of the 6(2)-6(1) and 5(2)-5(1) E transition of CH3OH toward the Orion-KL region with an angular resolution of 3 arcsec and a frequency resolution of 12 kHz (0.15 km/s). They are shown to lie over an area of approximately 40 arcsec, as previously shown by Matsakis et al. (1980). A detailed comparison exhibits a qualitative agreement of the intensities and sizes with the previous map. In 11 of 14 cases, the positions, flux densities, and radial velocities of the 6(2)-6(1) E and 5(2)-5(1) E maser components agree. Although individual maser emission regions are unresolved in the present 3-arcsec beam, the variation of position with velocity within what is thought to be a single feature implies clustering of masers on scales of less than 3 arcsec. The most intense feature has a brightness temperature in excess of 100,000 K. The best agreement is within the map of the 8(0)-7(1) A transition of methanol.
