1. Assumptions
The assumption is the Michelle Instrument will already have
been through the liquid Nitrogen pre cool circuit close to the north
pier on the telescope and will probably have been through a health
check using normal software i.e. until it is basically cold and
fully operational. There is some requirement to minimise the time
the system will be disconnected from the coolers so that it does
not warm up too much but as the balancing requirements for the telescope
will require considerable time anyway perhaps this is not a problem.
