50CORON - Clear CCD

Description

The 50CORON imaging mode is useful for imaging faint targets situated next to bright ones.  The STIS CCD optics include a Lyot stop, which suppresses the wings of the PSF.  See Section CCD Clear Imaging—50CCD for sensitivities, throughputs, and encircled energies.  See Section 12.11 for the PSF and for a discussion of coronagraphic imaging.  Figure 12.6 shows the layout of the 50CORON aperture and the positions of the wedges.
