The HST/WFC3 IR Point Spread Function: A 13-Year
Empirical Characterization for Precision Astronomy in
the JWST Era
Telescope’s Wide Field Camera 3 infrared channel (WFC3/IR) point spread function,
analyzing 512 high-quality PSF measurements from 13 years of archival observations
(2010–2023). Using a statistically robust sample across multiple filters with precise
focus values (–2.0 to +2.0 µm), we quantify: (1) focus-dependent FWHM variations of
18.7% across the operational range, following a parabolic relationship with minimum
at focus =–0.2 µm (FWHM(focus) = 1.92 + 0.031·foc
