Scientific paper
Following the insertion of WFC3 into the HST observatory during Servicing Mission 4, we aligned the UVIS and IR channels, independently, to the telescope early in the SMOV4 instrument verification campaign. Using a variety of techniques, and accounting for the OTA temporal focus variation, we adjusted the instrument corrector mechanisms to optimize image quality. The IR channel alignment observations, analysis techniques and resulting adjustments are described herein; alignment of the UVIS channel is treated in a separate report.
