Fig. 2

Continuum maps obtained toward Orion-KL with the Plateau de Bure Interferometer. The clean beam is shown in the bottom left corner of each map. The first contour and the level step are 15 mJy beam-1, 170 mJy beam-1, 70 mJy beam-1, and 100 mJy beam-1 at 101.45 GHz, 203.41 GHz, 223.67 GHz, and 225.90 GHz, respectively. In each map, positions of the BN object (αJ2000 = 05h35m141094, δJ2000 = −05°22′22
724) and the radio source I (αJ2000 = 05h35m14
5141, δJ2000 = -05°22′30
575) (Goddi et al. 2011) are indicated. The maps have not been observed with the same center (see Table 1).
