1. MSE Radial Resolution with ‘Dirty’ Lens

2. MSE Radial Resolution with ‘Clean’ Lens
FWHM about a factor 2-3 smaller.
‘Tails’ are reduced.
Tried various fitting functions … settled on a spline

4. The Poor Spatial Resolution of the Dirty Lens Changes the
Measured Field-Line Pitch Angle by up to ~0.5 degrees.

5. There is Little Difference in Inferred Pitch-Angle between a Local
And a Radially-averaged MSE Measurement with a Clean Lens

6. Measured MSE Light is the Convolution of the Diagnostic Response (spatial resolution) and MSE Emission Intensity Profile
At edge: emission intensity weighted to inside of viewing region.
At center: emission intensity weighted to outside of viewing region.
Beam-into-gas: emission intensity weighted to outside of viewing region.
