A piece of computer software used at the David Dunlap Observatory at the University of Toronto, one of Canada’s most important astronomical observatories The David Dunlap Observatory opened in 1935 as the result of a bequest from the wife of David Dunlap. The telescope was a 74 inch (188 cm) reflector built by Grubb Parsons of Newcastle-upon-Tyne in England. The 74 inch was then the largest telescope in Canada (surpassing the 72 inch telescope of the Dominion Astrophysical Observatory in Victoria) and became the second largest in the world after the 100 inch Hooker Telescope of the Mt. Wilson Observatory outside Los Angeles. DDO's reputation grew and following WWII, it began to graduate most of the astronomers produced in Canada with University of Western Ontario far behind. Beginning in the 1960s a number of other astronomy departments were created but UofT/DDO held its place, a position it probably still holds. The DDO had a good technical staff which gave them an advantage and, with most of the 1940s to early 1970s top astronomers coming from UofT, grants from NRC and then ENSERC were almost guaranteed and allowed UofT's top astronomers -- Hogg, van den Berg, Fernie, Bolton, Kamper, Martin, etc. to acquire or build some of the best equipment available in university observatories. For optical observatories, only the DAO had technical staff and budgets that surpassed those of DDO. In 2007, citing increasing light pollution, the University of Toronto announced plans to sell the Observatory property. In June 2008, it was sold to Corsica Development Inc., a subsidiary of Metrus Development Inc. and the Observatory was closed. In 2009 the Observatory buildings and 80% of the site were designated a cultural heritage landscape. Also in 2009 Corsica and the Royal Astronomical Society of Canada, Toronto Centre announced an agreement allowing the RASC to provide public education and outreach programs at the observatory, and to operate the 188 cm telescope. - Fonction

A computer program for a 9-track tape controller board. - Technique
-
Computer software for an unknown computer used with an astronomical measuring engine, the Perkin-Elmer PDS machine. The TX-8 was a high speed 9-track tape controller for the PC, XT, AT and 386 and compatible personal computers. The Perkin-Elmer PDS machine was a device for digitally measuring photographs, used to measure both stellar and galactic spectra as well as direct images of the sky taken with the DDOs 74 inch telescope and plates acquired by Sidney Van de Burgh at the 48 inch Mt. Palomar Schmidt telescope. - Notes sur la région
