Notes. (1) index name; (la) variation of the UV index due to a 0.1% young population on top of 99.9% of 7 Gyr population; (2) redshift range in which the index is within the spectral range of the WEAVE spectrograph (zmax = 0.8); (3) reference for indices definition: (a) Fanelli et al. (1992), (b) Chavez et al. (2007), (c) Gregg (1994), (d) Balogh et al. (1999), (e) Worthey et al. (1994).
