\caption{\label{jcmt_parameters}Line parameters from the JCMT and CSO observations. The positions are offsets to the dust peak emission at $\alpha_{2000}$~$=$ $\rm 15^h54^m08\fs50$, $\delta_{2000}$~$=$ $-02^\circ52^\prime48^{\prime \prime}$. For non-detected lines we give the 3$\sigma$ upper limit. For JCMT and p-\ddhpb at CSO, we give both the Monte Carlo (MC) and the LTE~column density estimates.}
