Abstract

The cosmic-ray database, CRDB, has been gathering cosmic-ray data for the community since 2013. We present a new release, CRDB v4.1, providing many new quantities and data sets, with several improvements made on the code and web interface, and with new visualisation tools. CRDB relies on the MySQL database management system, jquery and table-sorter libraries for queries and sorting, and PHP web pages and AJAX protocol for displays. A REST interface enables user queries from command line or scripts. A new (pip-installable) CRDB python library is developed and extensive jupyter notebook examples are provided. This release contains cosmic-ray dipole anisotropy data, high-energy p¯ / p upper limits, some unpublished LEE and AESOP lepton time series, many more ultra-high energy data, and a few missing old data sets. It also includes high-precision data from the last three years, in particular the hundreds of thousands AMS-02 and PAMELA data time series (time-dependent plots are now enabled). All these data are shown in a gallery of plots, which can be easily reproduced from the public notebook examples. CRDB contains 316,126 data points from 504 publications, in 4111 sub-experiments from 131 experiments.

Funding Information:
We warmly thank the continuous support and feedback from many of our colleagues, who point out typos and mismatches in CRDB. We also thank the AMS-02 Collaboration for providing their data as csv tables ( https://ams02.space/publications ), which greatly eases the preparation and upload of these data in CRDB. This research has made use of NASA’s Astrophysics Data System Bibliographic Services. We acknowledge the NMDB database ( www.nmdb.eu ), founded under the European Union’s FP7 programme (contract no. 213007) for providing data; NM data from Oulu are provided by the Sodankyla Geophysical Observatory (see also https://cosmicrays.oulu.fi/readme.html ) and those from Thule by the University of Delaware Department of Physics and Astronomy and the Bartol Research Institute.
