Query: galstreams: A Library of Milky Way Stellar Stream Footprints and Tracks   Nearly a hundred stellar streams have been found to date around the Milky Way
and the number keeps growing at an ever faster pace. Here we present the
\galstreams\ library, a compendium of angular position, distance, proper motion
and radial velocity tracks for nearly a hundred (\Nunique) Galactic stellar
streams. The information published in the literature has been collated and
homogenised in a consistent format and used to provide a set of features
uniformly computed throughout the library: e.g. stream length, end points, mean
pole, stream's coordinate frame, polygon footprint, and pole and angular
momentum tracks. We also use the information compiled to analyse the
distribution of several observables across the library and to assess where the
main deficiencies are found in the characterisation of individual stellar
streams, as a resource for future follow-up efforts. The library is intended to
facilitate keeping track of new discoveries and to encourage the use of
automated methods to characterise and study the ensemble of known stellar
streams by serving as a starting point. The library is publicly available as a
Python package and served at the galstreams GitHub repository.
