[Comm2011] illuminationcorrections workplan Groningen

[John P. McFarland]

Hi Gijs,

I cannot see the objects you created for the illumination correction (e.g., 
reduced frames, catalogs, etc.).  Could you please check to see if you 
published them?  We would like to investigate them.  Thanks!

Cheers,


-=John
