Impact of the decreasing resolution on the bar analysis, using PGC049413 as an example. On the left are the galaxy images, and their respective derived ϵ profiles are shown at the right. At the top of each image, the ratio of a_{bar,  true} to the FWHM is indicated. The first row shows the results from DESI, succeeded by the results from low-resolution F200W images in the rows below. The DESI ϵ profiles are plotted with dashed gray curves in the right panels. The intrinsic bar position is denoted as the vertical dashed gray line. When a bar is successfully identified, it is marked in the image by an ellipse and indicated in the profile by a vertical solid line.
