Tone curves in exposure tab

Hi,

unfortunately I cannot find any discussion of the tone curves in RawPedia. I wonder, why two curves are available. And what do the various options like standard, weighted standard etc. do?

Any information on the use of these curves would be appreciated.

Thanks Alberto! I was just looking under the headlines. There was exposure, then gamma, shadow/highllights tone mapping and all the other tools in this tab, but not tone curves.
