a Nominal dispersions for G7, G8, G14, and G15 are $\sim $1.5, 1.1, 1.4, and 3 Å pixel-1, respectively. Hence, 3 pixel resolutions at the H$\alpha $ line are: G7: $\sim $4.5 Å, G8: $\sim $3.4 Å, G14: $\sim $4.2 Å and G15: $\sim $9.1.
b G14 is sensitive in 3275-6100 Å band and used for blue spectra.
