> Detailed Description :
> I have edited the focus offset for the NB_659 in the data base:
> 
> I have -0.021 offset between the image analyses and the focus sequence. With a field curvature (half value between center and edge) of 0.06 I have estimaged 540nm = 1000 *  (-0.021 + +0.006)  / -0.028
> 
> The value is edited in locics1:Appl_data:OMEGACAM:ICS:DEVICES:FILT.fltAvailable (row 30, columns focus and focusADS)
> 
> The change should be archived asap.
> 
> 
> The images of the focus sequence indicate that this is a good compromize (round, sharp images from the center to the edge of the FOV)
