S/N values in specific spectral pass bands.

Wavelength N 4 Vesta 12 Victoria Europa

Acquisition year 2014 2014 2015

Strömgren b 4 210 ± 20 110 ± 10 470 ± 200
Strömgren y 4 280 ± 30 130 ± 10 440 ± 130
Johnson R 9 270 ± 40 150 ± 20 460 ± 150
Johnson I 9 250 ± 40 130 ± 20 430 ± 170

Notes. The reported S/N represents the mean S/N of N continuum regions in the spectrum. The standard deviation from those subsets is given as uncertainty. The passband gives the location of the regions without stellar or telluric lines that were used to estimate the S/N for the compiled solar median spectrum from the observations of the asteroids Vesta and Victoria and the jovian moon Europa.
