Notes. The table is ordered after surface mass density and gives the properties of the first ten clouds. The offsets, x and y, are calculated with respect to the center position of M33 of RA(2000) = 01^h33^m50.62^s and Dec(2000) = 30° 39′46.45″. See Sect. 4 for details on the calculation of the listed quantities. The full table is provided in electronic form at the CDS.
