The list often discusses the fact that astronomers need UT1. Does anyone
know astronomer's requirement for pointing accuracy. Does anyone know of a
document that discusses how astronomers receive ΔUT1 and incorporate it in
telescope pointing systems. (For telescope, read any astronomical instrument
that needs precise pointing.)
