52X0.1 Aperture

Description

This slit is supported with use of the first-order gratings and prism. This aperture is the 2 pixel-wide slit in the dispersion direction for the CCD first-order modes.

Special Considerations

Observations with this slit require a PEAKUP prior to science observations.
