a) Comparison between the observed KLF in the reference field (red filled circles) and the simulated KLF from star counts modeling (blue filled triangles). If the star counts represent the number N of stars in a bin, the associated error bars are . The KLF slope (α, see Sect. 4.5) of the reference field (solid line) is 0.34 ± 0.01. The simulated model (dashed line) also gives the same value of slope (0.34 ± 0.02). b) The KLF for the CrW region (filled red circles) and the simulated star counts (blue filled triangles). In the magnitude range 10.5−14.25, the best-fit KLF slope (α) for the CrW region (solid line) is 0.31 ± 0.01, whereas for the model (dashed line), after taking extinction into account, it comes out to be 0.36 ± 0.02.
