The LSST_23.5 astronomical image dataset is aGalaxy Image Deconvolution for Weak Gravitational Lensing with Unrolled Plug-and-Play ADMMThe experimental dataset used in " Galsim  and COSMOS  Simulations are created based on ground-based observations.

The original images are randomly cropped and rotated to simulate weak lensing effects, and then convolved with random atmospheric and optical PSFs and scaled in brightness before adding Gaussian noise. Finally, all images are downsampled to the pixel scale of LSST.
