An extinction-corrected CMD for NGC 7789 using GAIA photometric data. As identified in the plot legend, the star-shaped symbols show the red giants of this study. The reddening vector shows the direction and length by which we shifted the stars on the CMD to correct for interstellar reddening effects.
