spike: A tool to drizzle HST, JWST, and Roman PSFs for improved analyses

Ava Polzin

A point spread function (PSF) describes the distribution of light for a pure point source in an astronomical image due to the optics of the instrument. An accurate PSF is key for d…

A Method To Characterize the Wide-Angle Point Spread Function of Astronomical Images

Qing Liu, Roberto Abraham, Colleen Gilhuly +14

Uncertainty in the wide-angle Point Spread Function (PSF) at large angles (tens of arcseconds and beyond) is one of the dominant sources of error in a number of important quantitie…
