Figure 5

Optical images (left) and profiles of pump beam power and optical emissions (right). The left column shows images taken for the various heater beam pointing directions indicated in the right column. The red dashed line shows the location at which the optical emissions shown in the right panels are measured. The right column shows the pump beam ERP (green) and 630 nm emission intensity (blue) as a function of zenith angle. The red solid line shows the magnetic field-aligned direction.
