... Sizes of spectra The number of spectra that are `spoiled' by overlaps depends on the contrast ratio reached by the MEMS device, the area on the sky covered by an individual spectrum and on the number density of potential spoilers at a given magnitude. ... 4-- NIRSpec contrast and confusion limits 1 low resolution 0.8 0.6 0.4 0.2 0 1 hi resolution 0.8 0.6 0.4 0.2 0 20 Figure 3: Probability that spectra are contaminated at the Galactic pole as a function of the magnitude of the target galaxy. ...
