Two examples of distance-corrected colour magnitude diagrams of the subset of the GCNS catalogue for which XPSP can be obtained, using combinations of broad (left panel) and medium width (right panel) passbands of the C1 system. Black arrows highlight the location of the Jao gap (Jao et al. 2018), which is clearly visible in both diagrams, showing the high precision of the XPSP in these bands.
