Integrated ¹³CO maps of the two components seen towards AGAL340.188-00.411 (see lower panel of Fig. 16). The emission has been integrated over a velocity range of twice the FWHM line width of each component. The yellow contours show the distribution of the 870 μm emission mapped by ATLASGAL. In this case, there is a better morphological correlation between the dust emission and the CO emission found at −48.9  km s^-1 than with the CO emission at −120.6  km s^-1. Therefore, we assigned a velocity of −48.9  km s^-1 to this clump.
