The First Cambridge Catalogue of Radio Sources (1C) refers to the catalogue listed in the article Ryle M, Smith F G & Elsmore B (1950) MNRAS vol 110 pp508-523 "A Preliminary Survey of Radio Stars in the Northern Hemisphere". [1] The Cavendish Astrophysics Group (formerly the Radio Astronomy Group) is based at the Cavendish Laboratory at Cambridge University. ... The University of Cambridge (often called Cambridge University), located in Cambridge, England, is the second-oldest university in the English-speaking world. ...
The 1C catalogue listed about 50 radio sources, detected at 3.7 m with a fixed meridian interferometer. According to researchers at the Special Astrophysical Observatory[2], most of the sources from 1C were later recognized to be the effect of confusion, i.e. they were not real objects.
The survey was produced using the Long Michelson Interferometer at the Old Rifle Range in Cambridge in 1950. This device operated primarily at a wavelength of 3.7 metres, and was operated using Ryle's phase switching technique. F. Graham Smith also used the interferometer to measure the electron density in the ionosphere. Map of the Cambridgeshire area (1904) The city of Cambridge is an old English university town and the administrative centre of the county of Cambridgeshire. ... 1950 (MCML) was a common year starting on Sunday (link will take you to calendar). ... Sir Martin Ryle (September 27, 1918 – October 14, 1984) was a British radio astronomer who developed revolutionary radio telescope systems (see e. ...
The catalogue from this survey is only informally known as the 1C catologue.
1C was one of the first Russian private companies to be awarded with the Russian Federation Government Award in Science in 2002 for development and implementation of 1C:Predpriyatiye.
1C is best known outside of Russia perhaps for developing the famous IL-2 Sturmovik line of flight sims that includes Forgotten Battles and Pacific Fighters; 1C has a long history of in-house development, as well as funding independent developers.
Other notable games funded and/or developed by 1C include Soldiers: Heroes of WWII and the upcoming sequel Faces of War, Vivisector, the Silent Storm series, the Pirates of the Caribbean video game, and more.
1C Company is widely acknowledged as a game developer and has 2 internal studios.
Internal developments of 1C include Konung Legends of the North, IL-2 Sturmovik, IL-2 Sturmovik: Forgotten Battles and Wartime Command.
Currently we develop together with 1C Company our first person action title You Are Empty, created on our own powerful DS2-Engine, utilizing the newest software technologies and features of next-generation video-accelerators.
