Notes. The third column gives the upper energy level and the fourth column the line strength. The fifth and sixth column yield the peak values and integrated intensity values derived from the observed line profiles. In the last column, the expansion velocity is derived from the expanding shell fit. For the peak flux and the integrated intensity, the values derived from the main-beam temperature ( $T_{{\rm MB}}$) and the mean brightness temperature estimate (Mean ${T_{\rm b}}$) are given.
