only 11 Rrs for OLCI?

Hi everybody,

I want to know why I got only 11 Rrs for OLCI using L2gen commande line and how I can get Rrs of the other bands.

Well, because there are only 11 bands shorter than 720nm.  By default, the l2gen program will not produce Rrs for NIR bands.
You can ask l2gen to produce Rrs for all bands via l2prod=Rrs_nnn.  Keep in mind, several bands will fail or produce suspect data (e.g. 940 is the water vapor band)
The bands used in the aerosol determination for the atmospheric correction (779 and 865 by default) will return the Rrs output from the NIR correction algorithm and not a "measured' value.
