\caption{MAMBO map details. For each core the products ``number of  maps'' $\times$ ``array type'' list how often a core was observed  with which array (``37'' for MAMBO-1 and ``117'' for MAMBO-2). Several products are given if a dense core was observed with   both arrays. The last column lists the minimum noise level in a map   after smoothing to $20 \arcsec$ resolution.}\label{tab-survey:observations}
