[KIDS] KiDS-N vs SDSS

[Gijs Verdoes Kleijn]

Dear Mario and Jeffrey,

Conclusion at yesterday's telecon part on KiDS-SDSS comparison:
-Jeffrey has gained experience and has Astro-WISE code in place to do 
KiDS-N vs SDSS comparison massively.
-Mario has code and gained experience how to do the comparison best 
(MAG_AUTO vs APER, statistics etcetera).

I propose as next step that Jeffrey and Mario exchange their experience 
and then use this mailinglist thread to propose next steps.

Best wishes, Gijs
