Table 3.
Parameter cuts applied to model fits.
| Model | Parameter cuts |
|---|---|
| All models | Mean residual, < 0.02 mag/arcsec2 |
| Model ellipticity, < 0.6 | |
| Superellipse index, 1.5 < ce < 3.5 | |
| Model colour, 0 < μg − r < 2 | |
| Elliptical | Model colour, μg − r > 0.5 |
| Sérsic index, n > 1 | |
| Disc-only | Model colour, μg − r < 0.6 |
| Bulge+Disc | Bulge colour, μg − r > 0.5 |
| Bulge colour – Disc colour > 0 | |
| Central brightness, Bulge > Disc (r band) | |
| Bulge/Disc luminosity ratio < 0.5 (r band) | |
| Bulge+Bar+Disc | Bulge and Disc cuts are the same |
| Bar ellipticity > 0.3 | |
| Bar colour, 0.5 < μg − r < 2 | |
| Bar semi-major axis > Bulge radius | |
| Bar superellipse index, 1.5 < ce < 10 | |
| Bar Sérsic index, n < 0.9 | |
Notes. The first row contains cuts that apply to all models, subsequent rows contain cuts specific to each model. The colour of the model μg − r, is calculated by subtracting surface brightness in the r band from the g band.
