Scientific paper

A 42arcsec resolution continuum map of Orion A, at 23 GHz, and H110α line data toward, and at 4arcmin from the continuum peak are presented, as well as measurements of the H39α, 41α, and 42α lines. Toward the peak, the electron temperature, averaged over 2arcmin, is 8300K to 8600K, assuming electron densities in the range 5000 cm-3 to 7400 cm-3. If the H110α lines at 4arcmin from the peak are formed in LTE, Te there is 7600±200K. Comparisons are made with previous observations and models of the Orion H II region. Molecular line results are combined with the continuum data to produce a simplified picture of the H II molecular complex.
