Comparison of G230MB and G230M

The trade-off between using the G230MB or the G230M (which uses the NUV-MAMA) grating modes, depends sensitively on the science goals and your source properties. Figures below show a direct comparison of some of the properties of the G230MB and G230M modes. See also Comparison of G230LB and G230L.

Figure 13.28: .Comparison of Limiting Magnitudes and Fluxes for G230MB and G230M. Plotted are the limiting source magnitudes and fluxes for G230MB and G230M to achieve a signal-to-noise ratio of 10 in 1 hour per 2 dispersion pixels and integrated over the PSF.
