\caption{\label{flux1.5}Main-beam intensities, peak temperatures, and width for the detected transitions towards L1448N, L1448mm, and L1157mm. The errors on the fluxes were computed as the quadratic sum of the statistical error and the calibration uncertainty (see text). Upper limits are 3$\sigma$. Upper limits for lines not detected in any of these three sources can be found in Table~\ref{flux2}. }
