The 50CORON
imaging
mode is useful for imaging of faint targets next to bright ones. The STIS CCD optics include a Lyot stop, which suppresses the wings of the PSF. See CCD Clear Imaging-50CCD for sensitivities, throughputs, and encircled energies. See Chapter 5 for the PSF and for a discussion of coronographic imaging.
Recommended for broad-band coronographic imaging
