The Ohio Sky Survey and other radio surveys

Section I indicates the importance of astronomical surveys and comments on some of the earliest radio surveys. Section II describes the Ohio Sky Survey which totals over 19,000 radio sources at 1415 MHz. Methods of observation, data reduction and analyses of reliability and completeness are considered. Section III discusses the special Ohio sources with centimeter-enhanced (CE) spectra, including ones of the BL Lac type such as OJ287 and ones with high redshift such as OH471 and OQ172. Section IV relates the Ohio survey to other surveys, including data on other large surveys such as the Cambridge and Parkes surveys. Source counts are considered and statistics presented on the numbers of radio sources, identifications and radio astronomers. The last section, V, treats source nomenclature and the need for a single perpetual epoch.
