CH₃OH 2_k →  1_kv_t = 0 integrated intensity map combining PdBI and 30 m data. The emission is integrated over the 2_-1 →  1_-1E, 2₀ →  1₀A, and 2₀ →  1₀E transitions. First contour and contour spacing are 0.39 Jy beam^-1 km s^-1 (3σ), the dashed contours show the negative emission (− 3σ). The synthesized beam (62  ×  33; PA = 176°) is shown in the upper right corner. The dotted circle indicates the interferometer primary beam (52″).
