\tablefoot {The  CH$_3$OH lines detected in at least a source other than NGC~6334I are reported in Table~4. Note that we did not report the list of CH$_3$OCH$_3$~lines as they are detected in NGC~6334I only and are the focus of a forthcoming paper. For each source, we report the main beam temperature integrated intensity~$T_{\rm mb}\Delta v$ (K~km~s$^{-1}$), and the FWHM $\Delta v$ (km~s$^{-1}$) obtained by fittting the line with a gaussian. In parenthesis we report the rms over the same  integration interval of the line intensity. Only lines with rms larger than~3 are considered  detected, except in the case of NGC~6334I, where~1$\sigma$ was taken since  the rms is artificially higher because of the line-crowed spectrum. Upper limits refer to~1$\sigma$. \\
