Fink alert added values

In addition to the information contained in the incoming raw alerts (see ZTF alerts schema for example), Fink attached new information coming from the science module. This information is in form of extra fields inside the alert packet, and you would access to it the same way as any other fields. Below we summarise the fields added by the Fink science modules:

Field Type Contents
cdsxmatch string Counterpart (cross-match) in the Simbad database
rfscore float Probability to be a SN Ia based on Random Forest classifier (1 is SN Ia). Based on https://arxiv.org/abs/1804.03765
mulens.class_1 string predicted class by LIA for filter band g
mulens.ml_score_1 float probability of an alert by LIA (0 to 1) to be a microlensing event in filter band g using a Random Forest Classifier
mulens.class_2 string predicted class by LIA for filter band r
mulens.ml_score_2 float probability of an alert by LIA (0 to 1) to be a microlensing event in filter band r using a Random Forest Classifier

Over time, there will be more added values available - and feel free to propose new modules!
