Four years ago we started at Cerro Calán an extension of the objective prism survey carried out at Cerro Tololo Inter-American Observatory (CTIO) by Malcolm Smith a decade ago (Smith 1975, Smith, Aguirre and Zemelman 1976). Thanks to the kindness of Dr. P.S. Osmer, then Director of CTIO, we got on loan Smith's original plate collection. Searching his plate material we learned to recognize the most prominent emission line objects. We decided then to extend Tololo's original survey to an area of the southern sky large enough to be of statistical interest but small enough so it could be carried through with our very limited facilities at Cerro Calán.
