Age and metallicity as a function of the galactocentric distance. The latter is shown both in degrees (lower axis scale) and in parsecs (upper axis scale). The distances in parsecs have been obtained assuming a distance to NGC 6822 of 510 kpc (Paper I). Upper panel: look-back times of the 75 and 95 percentiles of the SFR as a function of the galactocentric distance. Numbers from 1 to 6 within the panel identify the corresponding fields. Lower panel: the mean metallicity for the same percentiles. The percentiles and the colour coding are the same as in the upper panel.
