Integrated intensity maps of the CH₃OH 8_0,8–7_1,6 (E_up = 97 K, left), CH₂DOH 17_1,16 e₀ – 17_0,17 e₀ (E_up = 336 K, middle), and CHD₂OH 7_0,1 e₁ – 6_1,1 e₁ (E_up = 74 K, right) lines for 881427. The color scale is shown on top of each image. The image is integrated over [−5, 5] km s−1 with respect to the V_lsr of source A. The white vertical line in the colorbar indicates the 3σ threshold. The source positions based on the continuum emission are indicated with the white stars. The white ellipse in the lower right of each image depicts the beam size and in the lower left a physical scale bar is displayed.
