Extinction towards the RC features.
| Region | RC1 | RC2 |
|---|---|---|
| (mag) | (mag) | |
| 50 km s−1 | 1.85 ± 0.01 ± 0.11(0.02) | 1.81 ± 0.01 ± 0.09(0.02) |
| 20 km s−1 | 1.97 ± 0.01 ± 0.12(0.02) | 1.94 ± 0.01 ± 0.11(0.03) |
| The Brick | 1.93 ± 0.02 ± 0.12(0.02) | 1.94 ± 0.03 ± 0.13(0.05) |
| Control 1 | 1.95 ± 0.01 ± 0.12(0.02) | 1.93 ± 0.01 ± 0.12(0.02) |
| Control 2 | 1.92 ± 0.01 ± 0.11(0.02) | 1.88 ± 0.01 ± 0.10(0.02) |
Notes. Sub-indices 1 and 2 indicate the bright and the faint RC features, respectively. The numbers in brackets correspond to the relative systematic uncertainty between values from the same region. They only consider different temperatures, surface gravities, and metallicities for the RC stars.
