In these plots, both hybrids are shown as 480 continuous anodes.  Anodes
1-240 represent anodes on the NEAR side, if you place the ladder in front
of you, with the four wafer half-ladder to the left:

      -----------------------------------------------------
      | 480  241 | 480  241 | 480  241 | 480  241 |

      |          |          |          |          |   
      | Wafer 1  | Wafer 2  | Wafer 3  | Wafer 4  | 3 wafer 1/2ladder->
      |          |          |          |          | 
      |          |          |          |          |
      ------------------------------------------------------
      |  1   240 |  1   240 |  1   240 |  1   240 |
      ------------------------------------------------------

So, your wafer 7 corresponds to my wafer 1, and so on.
From this picture, anodes 1-240 represent the SOUTH side of the ladder,
and anodes 241-480 respresent NORTH.  So, hybrid 1 in plots represents
south, and hybrid 2 represents north, if you match pedestals.

So, the hybrids are reversed with respect to the standard geometry.
