||
| TiO 8465 | [8405–8425]/[8450–8470] | a, b |
| VO 2 | [7920–7960]/[8130–8150] | a, c |
| VO 7445 | 0.5625[7350–7400]+0.4375[7510–7560]]/[7420–7470] | a, d |
| c81 | [8115–8165]/([7865–7915]+[8490–8540]) | a, e |
Notes. The spectral indices are computed from the average flux over the defined wavelength ranges.
