Notes.The columns give the element, wavelength, log flux in usual units, the line intensity relative to Hβ, and the combined transmission of the sky, telescope, filter, and detector at this wavelength. Note that the model fluxes have not been multiplied with the transmission. The Z, Y and J bands are dominated by one line (but for the Y band it is located at the edge of the filter). H and Ks have a scattering of fainter lines. The total contribution of emission lines to the in-band flux is also given. This is much higher for Y and Z than for the other three bands. Next to the band are indicated the effective wavelengths and the width of VISTA’s filters.
