52X0.1 Aperture

---

Description

This slit is supported with 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 scientific observations.
