fink-science 0.4.8

User-defined science module for the Fink broker.

Fink Science

This repository contains science modules used to generate added values to alert collected by the Fink broker. It currently contains:

• xmatch: perform a crossmatch of the stream with external catalogs
  • cdsxmatch: returns the SIMBAD closest counterpart of an alert, based on position using the CDS xmatch service (online).
  • gcvs: returns the closest counterpart of an alert in the General Catalog of Variable Stars.
  • vsx: returns the closest counterpart of an alert in the International Variable Star Index.
• random_forest_snia: returns the probability of an alert to be a SNe Ia using a Random Forest Classifier (binary classification)
• snn: returns the probability of an alert to be a SNe Ia using SuperNNova. Two pre-trained models:
  • snn_snia_vs_nonia: Ia vs core-collapse SNe
  • snn_sn_vs_all: SNe vs. anything else (variable stars and other categories in the training)
• microlensing: returns the predicted class (among microlensing, variable star, cataclysmic event, and constant event) & probability of an alert to be a microlensing event in each band using LIA.
• asteroids: Determine if the alert is a Solar System Object (experimental).
• nalerthist: Number of detections contained in each alert (current+history). Upper limits are not taken into account.
• kilonova: returns the probability of an alert to be a kilonova using a Random Forest Classifier (binary classification).

You will find README in each subfolder describing the module.
