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.
