Latitude variation of NUV star counts (per deg²) for both the observation and model simulation at l ~ 50°. The UV-IR stars, GALEX+SDSS stars, and model-predicted star counts are represented by solid circles, open circles, and solid line, respectively. The UV-IR stars and the GALEX+SDSS stars shown in the plot are for NUV magnitude errors <0.2. The error bars displayed in the model star counts are due to Poisson noise. The asymmetric errors in the UV-IR star counts which arise because of the propagation of photometric errors are not shown.
