In greyscale, the 3.1 mm continuum emission of G11.11P1. Top middle: contour image of the CH₃OH emission integrated under the line 2₁  →  1₁E. First contour and contour spacing are 0.66 Jy beam^-1 km s^-1 (3σ). The synthesized beam (60  ×  32; PA = 174°) is shown in the lower right corner. Bottom middle: contour image of the CH₃OH emission integrated under the 2_-1  →  1_-1E, 2₀  →  1₀A, and 2₀  →  1₀E transition lines. First contour and contour spacing are 0.45 Jy beam^-1 km s^-1 (3σ). The dashed contours show the negative emission (− 3σ). We also show spectra at four different positions; positions are given in each inset in parenthesis in units of arcsec.
