Abstract:
We have carried out a multiwavelength study of the plane of our Galaxy
in order to establish a star-forming-complex catalogue which is as
complete as possible. Features observed include Hα, H109α,
CO, the radio continuum and absorption lines. For each complex we have
determined the position, the systemic velocity, the kinematic distance
and, when possible, the stellar distance and the corresponding
uncertainties. All of these parameters were determined as
homogeneously as possible, in particular all the stellar distances
have been (re)calculated with the same calibration and the kinematic
distances with the same mean Galactic rotation curve. Through the
complexes with stellar distance determination, a rotation curve has
been fitted. It is in good agreement with the one of Brand & Blitz
(1993, Cat. J/A+A/275/67).

Note (1): These values represent the change induced in the kinematical
distance by an error of the systemic velocity of +5km/s and -5km/s
respectively.
Note (2): The excitation parameter quantifies the complex velocity ;
it is determined from the radio continuum flux.
