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 modules. 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 SNe Ia based on Random Forest classifier (1 is SN Ia). Based on https://arxiv.org/abs/1804.03765
snn_snia_vs_nonia float Probability to be a SNe Ia based on SuperNNova classifier (1 is SN Ia). Based on https://arxiv.org/abs/1901.06384
snn_sn_vs_all float Probability to be a SNe based on SuperNNova classifier (1 is SN Ia). Based on https://arxiv.org/abs/1901.06384
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
roid int Determine if the alert is a Solar System object

Details can be found at fink-science. Over time, there will be more added values available - and feel free to propose new modules!
