Illumination
Observation
- Comments
- partial polarization variable with wavelength (from monochromator gratings)
- Observation mode
- single spot
- Image size
- 20.0 x 20.0 $mm$
- Comments
- The observation spot size is for nadir geometry. Its elliptic size varies with ermegence angles with extent x as $20/cos(\theta _e)$ mm
