Overview of model components used in the photometric decomposition.
| Model component | Function |
|---|---|
| Point source | Gaussian with a 0.1 px width |
| Bulge | Sérsic |
| Disc | Exponential |
| Bar1 | Sérsic with generalised ellipses |
| Bar2 | Sérsic with generalised ellipses |
| Bar3 | Sérsic with generalised ellipses |
| Ring | Gaussian ring |
| Background | FlatSky |
Notes. The three bar components given are all parts of the same bar. In detail, bar1 is the main long part of the bar, bar2 is the broadened inner part of the bar, and bar3 is the very thin and long part (see text for details).
