... limits . These limits do not turn out to be as much of a concern as Taylor ( 1991a ) found them to be for giants . If the safe short - wavelength limit is 5000 Å for giants ( Griffin 1969 ; Oinas 1974 ) , then the equivalent limit for ...

... limit on the extragalactic continuum of X · I , < 2.0 × 10 W cm 2 sr . The smoothness of the observed spectrum gives an upper limit on the extragalactic line intensity of I < 5 × 10-13 W cm 2 sr for λ = 1.7-2.5 μm , except for a dead ...
