0.2X0.06 Aperture
Description
This slit is supported for use with the medium resolution echelle gratings, and is available-but-unsupported for the first-order gratings and the high resolution echelle gratings. It is two pixels wide in the dispersion direction for the MAMA echelle gratings, providing optimal spectral resolution and line profiles.
Special Considerations
Used primarily with the E230M and E140M gratings. Observations with this slit require a prior PEAKUP.
