We targeted fields centred on luminous AGN at 0.5<z<6.3 which were known or suspected to be hosted by massive galaxies, as potential signposts of high-redshift overdensities. The ACES protocluster sample was surveyed at a wavelength of 1.1mm with the AzTEC camera as a visiting instrument at the 15-m James Clerk Maxwell Telescope (JCMT;FWHM=18arcsec) in Hawaii and at the 10-m Atacama Submillimeter Telescope Experiment (ASTE; FWHM=30arcsec) in the northern part of Chile. The field towards 4C+41.17 was observed at the JCMT in 2005 December, and the other 16 fields were observed at the ASTE from 2007 May to October and 2008 July to December. Table 3 shows the source catalogue for the PKS1138-262 field. This list is in decreasing order of S/N and includes the measured 1.1mm flux densities and their deboosted fluxes. Tables A1 to A16 show the catalogues for the other ACES protoclusters.
