J (2MASS) −W1 (WISE) versus NUV CMD for the GALEX and WISE+2MASS cross-matched sources for the AIS fields towards the GC and the GAC. The matched sources are clearly separated in two groups indicating isolation of stars (J − W1 < 1.2) from the extra-galactic sources (J − W1 > 1.2). The vertical dashed line shows the limit that we choose for selecting the point sources (J − W1 < 1.2). QSOs are shown by blue crossed symbols (see the text).
