Sharpness (left) and χ (right) values as a function of Vega magnitude for all sources detected in the F625W filter. Gray vertical and horizontal lines are shown to demarcate which sources were stars or galaxies. Sources with a Vega magnitude brighter than 24 were determined to be stars if their sharpness was less than zero (bottom-left quadrant in the sharpness plot), while sources with a Vega magnitude fainter than 24 were determined to be stars if both their sharpness was less than zero and their χ was less than 1 (bottom-right quadrant in both plots). Sources determined to be galaxies are shown as gold points, while sources determined to be stars are shown as purple stars.
