The cross-match (XM) is a sophisticated task that links all the Gaia observations with entries in the source catalogue. The main objective of this project is to perform a comparative analysis of several clustering algorithms that will be part of the XM of the Gaia detections to sources.
The clustering results generated by each method will be compared against the true XM resolution provided by a simulator. Finally, a decision will be made based on the results of this comparative analysis regarding the selection of the clustering algorithm which best fits the XM requirements to be used in the Gaia data treatment
