Notes.

^(†)

Number of 6-min individual exposures.

^(‡)

Simultaneous thorium-argon (ThAr) or Fabry Perot (FP) reference.

^(††)

Airmass evolution during the observation sequence.

^(∗)

Median of the signal-to-noise ratio per pixel at 392 nm (pipeline order # 2), 527 nm (# 42), and 673 nm (# 67).
