Advantages of the Blue Cable

The blue cable has good spectral response blueward of 7000 Å down to the atmospheric cutoff (see Figure 7).

A 3 arc-second aperture was selected to provide some compensation for atmospheric dispersion while not significantly impacting on the level of the sky contamination. The need for sky suppression is not as significant in the blue spectral region as in the redward bandpasses.
