Estimated stellar mass from the added stars for different KLF slopes. Slopes of Buchholz et al. (2009) (for different stellar populations) are shown in green, NS10 in yellow and our fitted slope in purple. A limit imposed by the enclosed mass within the S2 orbit is plotted as horizontal dotted (gray) and dash-dotted (red) lines from Gillessen et al. (2009b) and Mouawad et al. (2005), respectively.
