Comparison of G230LB and G230L
The trade-off between using the G230LB or the G230L (which uses the NUV-MAMA), depends sensitively on the science goals and your source properties.
The NUV-MAMA is solar insensitive, whereas the CCD is not.
Figure 13.22: Comparison of Limiting Magnitudes and Fluxes for G230LB and G230L. Plotted are the limiting source magnitudes and fluxes for G230LB and G230L to achieve a signal-to-noise ratio of 10 per 2-pixel spectral resolution element integrated across the PSF, in 1 hour. The prediction due to the Charge Transfer Inefficiency (CTI) effect, computed for the year 2005, is also shown.
