Comparison of r-band images for TDE host galaxies ASASSN-19dj (left) and PTF09ge (right) from different surveys. The top row display images from SDSS DR7, while the bottom row shows images from DECaLS (for ASASSN-19dj, bottom left) and UNIONS (for PTF09ge, bottom right). The side-by-side comparison clearly demonstrates the significantly enhanced resolution of the DECaLS and UNIONS imaging relative to SDSS. An angular size reference is provided in the bottom-right corner of each panel.
