Abstract

Distances are key to determine the physical properties of sources. In the Galaxy, large (>10000) homogeneous samples of sources for which distance are available, covering the whole galactic distance range, are still missing. Here we present a catalog of velocity and distance for a large sample (>100000) of Hi-GAL compact sources. We develop a fully automatic Python-package to extract the velocity and determine the distance. To assign a velocity to a Hi-GAL compact source, the code uses all the available spectroscopic data complemented by a morphological analysis. Once the velocity is determined, if no stellar or maser parallax distance is known, the kinematic distance is calculated and the distance ambiguity (for sources located inner the Solar circle) is solved with the HII self-absorption method or from distance-extinction data. Among the 150223 compact sources of the Hi-GAL catalog, we obtained a distance for for 124069 sources for the 5-sigma catalog (and 128351 sources for the 3-sigma catalog), where sigma represents the noise level of each molecular spectrum used for the lines detection made at 5-sigma and 3-sigma, to produce the respective catalog.
