You will find 4 notebooks:\n\n- [Introduction](introduction.ipynb): Describe the basics to manipulate alert data\n- [KN-LC filter](KN-LC_filter.ipynb): Candidates from the filter using the kilonova classifier\n- [KN-Mangrove filter](KN-Mangrove_filter.ipynb): Candidates from the filter using a crossmatch with Mangrove galaxies\n- [KN-rate-based filter](KN-rate-based_filter.ipynb): Candidates from the rate-based filter\n\nAlert data are located under [data](data/). Note that during this period, Fink received 29,161,507 alerts from ZTF, and processed 10,273,271 alerts that pass the quality cuts.\n\nThe notebooks have dependencies in several external libraries.
