Similar plot as Fig. B.4. CH₃OH spectra were smoothed to the 30 m beam size of 25′′ to compare with the previous 30 m observations by Menten et al. (1988). Upper panels show the CH₃OH spectra and population diagram taken at the same position (, , J2000) used by Menten et al. (1988) and Mauersberger et al. (1988), which is located about 5′′ to the north of KL-W (denoted as KL-W_M). Lower panels show the CH₃OH spectra and population diagram taken at IRc2 (, , J2000) used by Jacq et al. (1993). Blue dashed lines indicate the fits with a fixed temperature of 130 K. Black dashed lines indicate a V_LSR of 8 km s^-1. Note that the CH₃OH column density derived toward KL-W_M is about 20% lower than that of IRc2.
