Algoritmos de Cross-Matching de Dados Astronômicos
Resumo
Este resumo descreve as principais estruturas de indexação para representar a esfera celeste em banco de dados e uma série de algoritmos de cross-matching usados em catálogos correspontes. Ao final do resumo, apresentamos um experimento com um dos algoritmos de matching utilizados pela comunidade.Referências
