Selection criteria for the GC candidates.
| Parameters | Values |
|---|---|
| Magnitude | 19.8 ≤ mg ≤ 26 |
| Concentration index (1) | 0.8 ≤ CIn ≤ 1.15 |
| Colour | 0.6 ≤ g − i ≤ 1.45 |
| 1.35 ≤ u − r ≤ 3.5 | |
| Difference from model (2) | ≤0.4 |
Notes. (1)CIn: normalized concentration index based on the difference in g-band magnitude between apertures of 6 and 12 pixels. (2)Maximum distance from the best-fit population synthesis model for spectroscopically confirmed GCs in the colour-colour diagram.
