Maps of molecular and continuum emission in CK Vul. Each map shows the weighted mean of the emission in multiple transitions of the given species and its isotopologues. Contours are drawn at 2.5, 5, 10, 20, 40, 80% of the emission peak in each map starting from a level above the respective 3 × rms noise. Continuum emission in bands 3 and 4 is imaged at a very high S/N, but is presented in the same linear color scale as the other maps. For completeness, we add a map of NH₃ obtained with VLA (right panel) with a non-circular restoring beam.
