Administrations cooperate to protect radio astronomy, given its sensitivity, long observations and known station locations (29.1 to 29.4); station locations and frequencies are notified (29.5); radio astronomy sites are chosen with regard to interference and reduce their own susceptibility (29.6, 29.7); administrations protect radio astronomy according to its status in the Table, using separation, shielding, directivity, time-sharing and minimum power, protect adjacent bands and avoid spurious emissions, and bear in mind susceptibility to space and airborne transmitters (Rec. ITU-R RA.769) (29.8 to 29.13).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
