Placas
Cada placa espectroscópica tem 640 espectros, observados simultaneamente. A placa em si é feita de alumínio, com um pequeno furo na posição de cada objeto a ser observado. Nós conectamos uma fibra óptica em cada furo. A outra extremidade da fibra óptica leva a luz ao espectrógrafo. A figura abaixo mostra onde cada fibra foi conectada à placa. A tabela abaixo mostra a lista de todos os objetos na placa por número de fibra, tipo e redshift. Clicar em qualquer um deles, mostrará a figura do espectro correspondente.
Esta página lhe dá acesso rápido a imagens GIF de espectros individuais de uma dada placa. Selecione uma placa no formulário abaixo e clique em um dos objetos da lista para ver o espectro. Se você quiser utilizar uma imagem no seu website, sinta-se livre, mas faça referência ao SDSS.
