VII/171 Michigan Emission-Line Objects (MacAlpine+ 1977-1982) ================================================================================ Curtis Schmidt-thin prism survey for extragalactic emission-line objects MacAlpine G.M., Smith S.B., Lewis D.W., Williams G.A., Feldman F.R. =1982ApJ...261..412M ================================================================================ ADC_Keywords: QSOs ; Galaxies, Seyfert ; Galaxies, Markarian Description: The objects of this catalogue were detected by using the 61-cm aperture Curtis Schmidt telescope in combination with a thin objective prism (1.8{deg}) at the Cerro Tololo Inter-American Observatory. The low-dispersion spectra (174nm/mm at H{beta}) cover the wavelength range between 5350 and 3400 {AA}, where the emission lines such that those of [OII], [OIII] and Ly{alpha} are visible. The objects could be detected up to 18th magnitude. Note that the list archived here is not the same as the published lists (see the "References" section below): the positions in the "catalog.dat" file are generally more accurate than those in the original publication and the origin for these is not known. In the printed lists of papers , information presented for each object also includes image dimensions from the Palomar Observatory Sky Survey, an estimated continuum apparent magnitude, a redshift estimate when feasible, or (for galaxies) a spectral classification which involves compactness, color, and line-strength parameters.
