Peak amplitude declines in QPEs.
| Source | Relative declinea | Time spanb | # Epochs |
|---|---|---|---|
| eRO–QPE1 | 4–10× | 3 yr | 6 |
| eRO–QPE2 | 1× | 3.5 yr | 5 |
| GSN 069 | 1.5× | 2 yr | 2 |

Notes. (a)Ratio of count rates in the first and last epochs of observation. Second, eRO-QPE2, did not show any conclusive decline. (b)Amount of time between first epoch and last epoch. The papers describing the relative declines are: eRO-QPE1 and eRO-QPE2 (Pasham et al. 2024b), GSN 069 (Miniutti et al. 2023b), eRO-QPE3 (Arcodia et al. 2024), and Ansky (Zhu et al. 2025).
