\caption{\label{flux}Main-beam intensities, peak temperatures, and width for the observed transitions towards NGC1333-IRAS4A, IRAS4B, and IRAS2. 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$\sigma$ (see text).}
