Parameters of the narrow-band imaging from July 25, 2019.
| Filter | Δλ | n | texp | ttot |
|---|---|---|---|---|
| [O III] | 496.5–501.5 | 23 | 155 | 59.42 |
| [O III]C | 509.0–519.0 | 5 | 65 | 5.42 |
| Hα | 654.0–661.0 | 29 | 35 | 16.92 |
| HαC | 659.0–665.0 | 10 | 31 | 5.17 |
Notes. For each filter, we give the wavelength range Δλ in nm (obtained from the GMOS website), the number of frames n, the individual exposure time texp in s, and the resulting total exposure time ttot in min.
