Channel maps of CH₃OH (2_2,1,0 − 3_1,2,0), H¹³CN (4-3), and SO (8₉ − 7₈) in the inner ~l.5″ region. The continuum contours are shown in gray and they are set at [10, 30, 100]σ_cont with σ_cont = 0.25 mJy beam⁻¹. The peak of the continuum is indicated by a cross. The red and blue contours correspond to positive and negative velocities respectively, expressed in km s⁻¹ with respect to the adopted systemic velocity V_sys (= 5.3 km s⁻¹ in the LSR frame). The contour levels are set at [7, 13, 20]σ for CH₃OH and H¹³CN, and [6, 10, 15]σ for SO with σ given in Table 1. The molecules shown here show rotation signatures at |V| < 3 km s⁻¹ in the inner regions or in the outflow emission.
