资源简介：
Isolated galaxy images generated with GalSim from parametric models extracted from the Hubble COSMOS catalog. These files contain images and data for 10 000 images of isolated galaxy: <strong>galaxies_isolated_10000_images.npy: </strong>numpy array of shape (10 000, 10, 64, 64), 10 000 images of size 64x64 pixels, in 10 filters (4 Euclid filters and 6 <em>ugrizy</em> LSST filters, in that order). Images contain Poissonian noise. <strong>galaxies_isolated_10000_data.csv: </strong>corresponding parameters: SNR: signal-to-noise ratio redshift: redshift of the galaxy e1: e1 parameter of ellipticity (e = e1 + i.e2) e2: e2 parameter of ellipticity (e = e1 + i.e2) mag: magnitude
