52X0.2F1 Aperture Description The same physical aperture as the 52X0.2 but used at the position of the smaller of the two fiducials. The fiducial bar can be used for spectroscopic coronagraphic observations. The throughput for the unocculted 52X0.2 aperture is given below. Special Considerations Observations using this slit do not need to be preceded by a PEAKUP.
