J − H color images of sources in tile “b214” of our DaoPHOT catalog before the photometric calibration (left), of the released DoPHOT catalog (middle, Alonso-García et al. 2018), and of our DaoPHOT catalog after the photometric calibration (right). The images are produced by smoothing the source J − H colors with a Gaussian kernel (FWHM = 30″).
