Features

Currently scludam is a work in progress. Modules and features already included are:

• fetcher: simple query builder to get data from the GAIA catalogue more easily, and some extra useful functions.

• stat_tests: set of 3 clusterability tests that can be used to detect the presence of a cluster in a sample.

• synthetic: classes that can be used to generate synthetic astrometric samples by specifying the distributions to use and parameter values.

• detection: classes that can be used to detect the presence of a cluster in a sample.

• shdbscan: soft clustering based on the HDBSCAN algorithm.
