Closure equation change around 2017-09-05

Elsa's logbook denotes the following change which coincides with the change in the closure equation agreement (no change of instrument, but the CM11 GHI sensor was moved to the tracker):

> 6/9 2017. CM11 til globalstråling er flyttet op på trackeren.


Start with Elsa's logbook entry dated 6/9 2017 and the attached image, then inspect the closure-equation handling around 2017-09-05. Determine whether moving the CM11 GHI sensor to the tracker accounts for the reported change; done means the expected equation behavior and any required project change are documented.
