LSE-77 is the ICD for the DM to Base Facility interface. This is an interface defining the physical requirements of DM at the Base Facility. It is an interface between DM and Telescope & Site.
The interface primarily concerns itself with space, power, and cooling requirements for the DM equipment for the Base Center and the Chilean Data Access Center.
The completion of this milestone will reflect the conclusion of an agreement between DM and T&S on the details of the physical requirements, with these details either added to LSE-77 or reflected in other change-controlled documents. In particular, the Base Facility Data Center Design Requirements document, LSE-239 reflects the roll-up of all subsystems' requirements for Base Facility accommodation.
