No. of bitstreams: 1 dissertacao1 - F.pdf: 19663712 bytes, checksum: b4d07b5a7a0e8418855eb7151fddc47c (MD5) Previous issue date: 2016-03-16 / This work shows the development of a graphical interface to reduce spectroscopic observations of peculiar galaxies present in the Catalogue of Southern Peculiar Galaxies and Associations (Arp and Madore 1987). The data have been observed with the Cassegrain spectrograph installed at the 1.6-m telescope of the Observat?rio do Pico dos Dias, Brazil/Laborat?rio Nacional de Astrof?sica ? Minist?rio da Ci?ncia Tecnologia e Inova??o (OOD/LNA-MCTI). The interface is called "PyOPD-Cass". In this project, the tasks present in IRAF package are sequenced together in order to produce calibrated data in flux and wavelength. Thus, the methodology used to reduce spectral data allows the user to quickly and easily insert all the necessary parameters for the spectral reduction process. The material developed in this work, within the concept of "pipeline", has the advantage of minimizing the time in the spectral reduction. As application of the computational process, we show only the spectral reduction to a selected set of 73 peculiar galaxies with emission lines observed over the long-term project carried out in OPD/LNA-MCTI ("Spectroscopic Study of Peculiar Galaxies and associations", OP2012A-009). The scientific results of these active galaxies will be discussed later in another study, already under development. All the development program was conducted in Python, further comprising PyRAF language and PyQt adapter as a basis for the final GUI architecture. / Este trabalho, aplicado na sub?rea de Astronomia Extragal?ctica, apresenta o desenvolvimento de uma interface gr?fica de redu??o de dados espectrais no ?ptico para Gal?xias Peculiares e Associa??es do Cat?logo de Arp e Madore (?A Catalogue of Southern Peculiar Galaxies and Associations?, 1987), que vem sendo observadas com o espectr?grafo Cassegrain instalado no foco f/10 do telesc?pio de 1,60m do OPD/LNA-MCTI (Observat?rio do Pico dos Dias/Laborat?rio Nacional de Astrof?sica ? Minist?rio da Ci?ncia Tecnologia e Inova??o). Denominamos a mesma neste trabalho de ?PyOPD-Cass?. Neste projeto de Computa??o Aplicada, as tarefas de redu??o de dados presentes no IRAF ser?o sequenciadas e agrupadas afim de produzir dados finais calibrados em fluxo e comprimento de onda. Dessa forma, constru?mos uma metodologia otimizada para a redu??o dos dados espectrais, a qual permitir? ao usu?rio a inser??o de maneira f?cil e r?pidade todos os par?metros necess?rios para o processo de redu??o espectral. O material desenvolvido neste trabalho, dentro do conceito de "pipeline", possui a grande vantagem de minimizar o tempo de redu??o espectral em rela??o ao processo empregado atualmente. Como aplica??o do processo computacional desenvolvido neste trabalho, ser? mostrada apenas a redu??oespectral para um conjunto selecionado de 73 gal?xias peculiarescom linhas de emiss?o observadas ao longo do projeto de longo prazo realizado no OPD/LNA-MCTI (?Estudo Espectrosc?pico de Gal?xias Peculiares e Associa??es?, OP2012A-009), de autoria do orientador deste trabalho dissertativo. Todo desenvolvimento de programa??o foi realizado no ambiente Python, integrando ainda a linguagem PyRAF e o adaptador de linguagem PyQT, como base para a arquitetura final da interface gr?fica.
