Scientific paper

HST focus has been monitored throughout the Observatory's life. The preferred technique is a phase retrieval method which solves for certain Zernike coefficients, usually focus, coma and astigmatism, from model fits to the nearly in-focus PSFs. Here, we discuss what data from the ongoing monitoring strategies and special observations tell us about modes and timescales observed in HST optical variations, and suggest examining the current scientific need for PSF characterization. As the primary purpose for this monitoring is to support accurate focus maintenance, we also present a picture of the current focus state of the Observatory.
