Default Plate curves... Ic2 & Ib?

In the following plate curves from 6JS6C What are Ic2 and Ib? I haven't been able to figure it out from the data sheet.

Ib is current in the "B" circuit or plate current.

Ic2 is grid2 current, i.e. screen grid current.

(I think c2 means someting like control element #2; or Ic2 could be an extension of Ic which is grid current or "C circuit" current.)

Thanks. That sucker really pumps out the current. The curves look pretty nice at first glance though low screen voltage (190) would I suppose preclude UL or triode operation. 31V heater version is available pretty cheap...
