Overview of the JWST/NIRCam F150W PSFs in COSMOS-Web. We stacked all available PSFs from Zhuang et al. (2024) and show the mean PSF (left), standard deviation (centre), and the coefficient of variation (right), calculated pixel by pixel. The PSFs have been re-binned to a pixel resolution of 0.03 ″/pixel, matching the resolution used for the synthetic image creation. The axes show the number of pixels, corresponding to 3″across. The colour bar shows the value of each pixel.
