Abstract

Images from the robotic Hex, southern sky survey, now underway at Cerro Tololo Inter-American Observatory, are analyzed and the survey is quantified in terms of two past catalogues, one of planetary nebulae and one of HII regions. Comparisons are made between brightness of objects measured on the survey's images and brightness or brightness class reported in each of the two catalogues. Also, comparisons are made between radial extent of objects as measured on the survey's images and reported size of the objects in the catalogues. Our survey can observe fainter parts of objects than have previously been catalogued.
