$\begin{figure} {\includegraphics[angle=0,width=7.5cm]{5132f1.eps} }\end{figure}$ Figure 1: OVRO map of the 2.7 mm continuum emission toward the core of L1206. The synthesized beam is $6\hbox{$.\!\!^{\prime\prime}$ }3\times4\hbox{$.\!\!^{\prime\prime}$ }8$ at $\rm PA=-27\hbox {$^\circ $ }$ and is drawn in the bottom left corner. The rms noise of the map, $\sigma$ , is 1.4 mJy beam^-1. The contour levels are $-5\sigma$ , $-3\sigma$ , 3 to 7 times $\sigma$ by $1\sigma$ , $10\sigma$ , 15 to 30 times $\sigma$ by $5\sigma$ , and $40\sigma$ . The error ellipse of IRAS 22272+6358A is indicated in white. The dotted circle represents the OVRO primary beam (50% attenuation level).
