Abstract: To ensure images generated by Rubin meet requirements for precision science, the observatory will use an active optics system (AOS) to correct for alignment and mirror surface perturbations introduced by gravity and temperature gradients in the optical system. To accomplish this Rubin will use out-of-focus images from sensors located at the edge of the focal plane to learn and correct for perturbations to the wavefront. Over the last year the wavefront estimation pipeline has been re-written from the ground up, increasing its flexibility, robustness, accuracy, and speed. We summarize these improvements and discuss preparations for active optics commissioning.
