Main kinematic properties of the different components of Mrk 1498.
| Component | PA | ΔV | σc | σavg |
|---|---|---|---|---|
| (degree) | (km s−1) | (km s−1) | (km s−1) | |
| Primary | 148 | 231 ± 12 | 191 ± 34 | 96 ± 24 |
| Secondary | 155 | 247 ± 5 | 22 ± 6 | 25 ± 9 |
| Tertiary | 150 | 228 ± 4 | 61 ± 10 | 37 ± 12 |
Notes. PA is the position angle of the kinematic major axis; ΔV is the observed peak-to-peak semi-amplitude of the velocity field; σc (σavg) is the central velocity dispersion within (excluding) the nuclear region (see Sect. 4.1). The quoted uncertainties for the velocity dispersion measurements are one standard deviation.
