MSE Radial Resolution with Clean Lens

• FWHM about a factor 2-3 smaller.
• Tails are reduced.
• Tried various fitting functions settled on a
  spline

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

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

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.
