C/2020 S3 Archives

Water production rate in comet C/2021 A1 (Leonard) as a function of time from perihelion. The points give the water production rate in s-1 from single images. The error bars give the 1-s formal random fitting errors for each value. There is a ~30% uncertainty from the model parameters and calibration. -- astro-ph.EP
