Results of image-level simulations in three representative fields of the OGLE GVS: GD1127.24 (603.6 stars arcmin⁻²), DG1076.26 (133.7 stars arcmin⁻²), and GD1758.31 (58.1 stars arcmin⁻²). Typical star surface densities are 1–2 orders of magnitude smaller than in the Galactic bulge fields (Mróz et al. 2019). Top panels: completeness of OGLE star counts as a function of magnitude. Middle and bottom: distributions of the dimensionless blending parameter.
