CMDs of NGC 5824 based on MegaCam photometry (left) and DECam photometry (right). In the MegaCam CMD, black dots correspond to the full sharp-cleaned data, while in the DECam CMD, black dots correspond to stars within 1′ ≤ R ≤ 35′, where R is the angular distance from the cluster center. The yellow shaded regions indicate the color and magnitude selection used to construct the cumulative LFs.
