Description:
We compiled a catalogue of infrared star clusters in the Galaxy, which
are most of them embedded. It condenses the growing literature
information. We also include in the sample infrared stellar groups
which are less dense than star clusters, such as those embedded in the
dark clouds Taurus-Auriga and Chamaleon I. We provide galactic and
equatorial coordinates, angular dimensions, different designations and
related objects such as nebulae. A total of 189 infrared clusters and
87 embedded stellar groups are included. A fraction of 25% of the
embedded clusters are projected close to each other in pair or triplet
systems, indicating that multiplicity plays an important role in star
cluster formation.
