# CHIME/FRB Catalog 2 (4,539 bursts, July 2018 to September 2023)

5,045 rows and 60 columns, published 14 January 2026, DOI 10.11570/25.0066. Exposure and fluence-threshold columns make rate and population inference possible. Supports luminosity-function and population synthesis, repeater classification from morphology, dispersion-measure statistics, periodicity searches on repeaters and extreme-value tests; Zhang and Wei (2026) and earlier Catalog 1 population
