Star counts of field NBF054. Left: K⁰LF of field NBF054. The black line shows the star counts corrected by completeness. For comparison, the gray line represents the uncorrected LF. The spline modeling the RGB is shown as dashed green lines. The fitting regions for the spline are shown as the vertical gray area. The LF with subtracted RGB LF is represented with the red area. Right: K⁰ LF with RGB subtracted is represented by the solid red histogram. Three Gaussians were fitted to the data: the left and right gray ones represent the early-AGB and RGB-bump, respectively; and the central green one represents the RC star counts. The solid black line represents the sum of the three Gaussians. The residuals to the fit are shown in the bottom part of the panel.
