... Judged by their instrumental profiles, spectrometers fall into two basic classes---Lorentzian and Gaussian---with many other line profile functions (sinc functions, Voigt functions, Airy functions, etc.) falling into one of these two categories in some limit. We demonstrate that the Rayleigh, Sparrow, and Houston resolution criteria are of limited use compared to the ``equivalent width'' of the line profile. ... Rayleigh criterion. ... All of these functions have continuous higher derivatives. ...
... Bad Astronomy . ... Bitesize Astronomy . ... We've come a long way from cluster to cluster! ... Some of these objects turned out to be star clusters of various types, and other were true nebulae, or clouds of glowing gas. ... Therefore, by their reasoning, these spiral nebulae must be part of our own Milky Way. ... An established and respected astronomer, Heber Curtis, defended the idea that the nebulae were ``island universes'', clusters of stars and gas in their own right like the Milky Way. ...
