GALEX far-ultraviolet image of SagDIG upon which the H i contours are overplotted. The 3 highest density H i clumps are the inner, open (green) contours, while the H i hole is highlighted as a shaded region. The right panel displays a closer view on the main body of SagDIG highlighting (i) the quadrangle HST/ACS field of view; (ii) the SagDIG derived center (see text) marked by a cross; and (iii) the 4 equidistant elliptical regions; used to extract and compare the stellar populations in the H i hole and the surrounding comparison fields.
