The two VM test campaigns show that we basically have a working instrument and test facility

• End-end functioning
• Blanket performance
• A pointe source looks like a point source
• The cal source illuminates the spectrometer detectors
• Imager and spectrometer are both in focus (or not)
• The wheels go round, the CCC moves, the sensors can be read out
• Throughput is what we expected to see
• We can get dark
• Checkout data chain
• Annealing of detectors, detector modes, pom heater works
• Enable on-going rationalisation and refinement of test plans
• DHAS used to reduce & analyse data, including cubes
• There is a lot of test data still to reduce and analyze
• There are 9 months in which to correct the MTS
