Detection

Detailed description (in draft version) of the Java code is available from Gaia WebSVN (Gaia password required), or here.



  • Currently, the detection system employs the following data:
    • G-flux observations - all available in given cycle
    • accumulated G-flux: mean and scatter


  • In the future it will also use:
    • accumulated BP and RP colours
    • morphology of the source
    • source motion flags
    • later in the mission: CU3, CU4, CU7 and CU8’s deliverables (information on motion, variability, astrophysical parameters)

Classification

At this stage all additional information from Gaia and later from other catalogues will be used for narrowing down the sample of interesting alerts.
