Luminosity function in Gaia G-band for the probable members in the entire studied region (run F1; bottom histogram), and only for NGC 2244 (within the cluster radius of r = 18′, excluding the probable members of NGC 2237; top histogram). The orange lines represent KDE distributions calculated with Silverman rule bandwidth. The upper distribution is shifted vertically by 0.1 for clarity. The completeness limit of the Gaia G-band with the distance modulus subtracted is shown as a vertical dashed line.
