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°) at the Cerro Tololo Inter-American Observatory. The
low-dispersion spectra (174nm/mm at Hβ) cover the wavelength
range between 5350 and 3400 Å, where the emission lines such that
those of [OII], [OIII] and Lyα 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.
