Notes. Uncertainties correspond to 3σ. Velocity uncertainties are of the order of the instrumental uncertainty (∼1.0 km s−1). Column density (N(Sp)) values for A-type methanol can be obtained by dividing the E-type methanol values shown in the table by the ISO number given at the next-to-last column, while the rest of the parameters are the same for both methanol symmetric types. The dash symbol (–) indicates that no nH2 was derived as the model is in LTE. An LSR velocity of 7 ± 1.0 km s−1 (see Sect. 2.3 and Fig. 1) was previously subtracted. Therefore, the real VLSR value, of about 7.8 ± 1.0 km s−1, depending on the component, is obtained by summing up these values.
