Observed area has been aligned with the PA (58°) of the galactic H I and de-projected using an inclination of 38°. The black crosses show the positions of those sources with (J − H)₀ ≥ 0.64 mag. Two circles at radius 2 kpc (9′) and 4.5 kpc (20′) have been imposed and the area divided into 6 segments in each annuli order to examine the TRGB, C/M ratio and [Fe/H] abundance within IC 1613 as a function of angle. The thick red line marks the approximate position of the PA in the de-projected image.
