Representative plots to show how S/N scales (for the HMM-VIS mode) with the number of exposures (exposure time), resolution, total throughput, and brightness of the source. Scalings were obtained by fitting a power-law function (x/x0)b to each S/N curve, where x represents one of the four quantities, x0 is the normalization (see text and Eq. (5)), and b is a power-law index.
