Top: g − r color profile of dE01+09 along its major axis. The red dashed horizontal line indicates the overall g − r color. Bottom: g-band surface-brightness profile of dE01+09 measured along its major axis. The solid blue line represents the best-fitting inner Sérsic component, while the red line shows the outer Sérsic component, and the inner plus outer is plotted in black. The overall global best-fitting profile is shown in green. Uncertainties on the data points are indicated by the error bars. The vertical dashed line represents the radius of the DESI fiber.
