Cut-outs of a $1\stackrel{\prime }{.}8\times 1\stackrel{\prime }{.}2$ region for a 10-year LSST-like survey with randomly placed sources (left) and the corresponding Euclid-like image (right). The PSF of the LSST-like image has FWHM of $0\stackrel{″}{.}7$, while that of the Euclid-like image is $0\stackrel{″}{.}16$. The effective background noise corresponds to a equivalent surface brightness of 27.50 mag arcsec⁻² for the LSST-like images and 24.71 mag arcsec⁻² for the Euclid-like images. Detailed information on the image simulation setup is provided in Table 1.
