a The first observations of NGC 1068 and the Circinus galaxy were carried out in SDT.
b In the meantime, more observations than those listed here have been obtained for several of the original SDT and GTO targets in Open Time.
Notes: the objects of the snapshot survey discussed in this paper are highlighted by boldface and marked by asterisks. The columns are: (1) the name of the galaxy (repeated from Table 1); (2) the date and (3) ESO programme number of the first successful observation or the last unsuccessful observation attempt; (4) the type of Coudé guiding used for the observations; (5) the number of successful fringe tracks obtained in SDT and GTO (without judgement on whether the data are useful or not) and (6) the result of the MIDI observations.
