Commisioning advice.

I am in the process of commissioning my BVR Photometry rig. So far I have measured the linearity of my CCD and it is linear to better than 0.4% from the bias level 5100 ADU to more than 64000 ADU. What I was wondering would be the best way to assess the rest of the set up and processing? I could not find anything in the CCD Photometry Manual so I propose imaging a number of Landolt fields and treat on of them as a variable to assess the performance of the filters etc. and my processing skills (using VPHOT). By doing Photometry on a star at different locations across the CCD I can assess the flat fielding.

Does this seem adequate and or what else should I do? Thanks for any advice you can give.

The filters I have are from FLI and are Johnson/Bessel which I assume are ok but I am not clear about if the difference between R and Rc is significant.
