This is a correction to the paper ‘SNAD catalogue of M-dwarf flares from the Zwicky Transient Facility’ (MNRAS, Volume 533, Issue 4, October 2024, Pages 4309–4323). In the original version of this manuscript, there were occasional errors in table 1 and fig. 1. The estimations of flare energies are calculated incorrectly: the correct value differs from the wrong one by a factor of 4.345. Although this error affects the values shown in table 1, it does not affect the other results of the paper. After applying the necessary correction, the conclusion is slightly modified: for 13 objects, we calculate the flare energy, ranging from |$\sim 1\times 10^{33}$| to |$\sim 93\times 10^{33}$| erg, which is consistent with the higher end of the energy distribution reported in the literature (Yang et al. 2017). There is also an error in the number of features in fig. 1: the correct number of used features is 53. We provide the updated versions of Table 1 and Fig. 1 in this correction.
Flowchart of the active machine learning method used to discover M-dwarf flares.
Bolometric energy estimations for the subsample of 13 flare candidates. The upper and lower energy errors were defined according to the Gaia EDR3 estimated uncertainties on geometric distances.
