The heating test of the ITMX with the RH and coincident HWS measurement was successful. The usual negative thermal lens was observed to form in ITMX in response to 4.035W total electrical power into the RH.

t = 0 is defined as when the RH was turned on. tmax is defined as when the value of spherical power peaks.

• The difference in SPHERICAL_POWER from t0 to tmax was -135 micro-diopters
• The difference in PRISM_X (YAW) from t0 to tmax was approximately  -0.25 micro-radians.
• The difference in PRISM_Y (PITCH) from t0 to tmax was approximately +2.1 micro-radians

The center of the lens is located at -[+2.1, -0.25]/(-135) m = [+16, -2]mm
