Based on a multi-core parallel processing paradigm, it is executed as a stand-alone command-line process or integrated within any generic data reduction/analysis pipeline. C3 provides its users with flexibility in portability, parameter configuration, catalogue formats, angular resolution, region shapes, coordinate units and cross-matching types.engGPLv3 public licenseSoftwarehttps://ascl.net/1610.0062016ascl.soft10006RFIS/05 - ASTRONOMIA E ASTROFISICA
