0.2X0.06 Aperture

Description

Supported slit for use with the medium resolution echelle gratings. This slit is two pixels wide in dispersion for these gratings, providing optimal spectral resolution and line profiles.

Special Considerations

Used with E230M and E140M gratings. Observations with this slit require a prior PEAKUP.
