[Comm2011] Dome lamp shutting off after 10 minutes during Gain?

[Ewout M. Helmich]

Hi Bernard,

It looks like all the gain templates for OCAM3 taken up to this point 
are wrong. After about 10 minutes, in the middle of the gain template, 
the lamp appears to shut down. Lamp header items then disappear, which 
resulted in errors during ingest here (note to Danny).

Also, the first gain template taken during OCAM3 has strange exposure 
times (see below). The exposure times for the 2nd and 3rd template are ok.
