SEDs of four spectroscopically classified stars. The top panel displays bright stars, and the bottom panel shows faint stars, with early-type stars on the left and late-type stars on the right. The blue lines denote the linear fit to the first four data points, while the orange lines represent the exponential fit to all seven data points. The grey shadows indicate the uncertainties of the exponential fits, as obtained from Monte Carlo simulations. The panels include notations for the CBDs for the stars.
