This is like learning that the Dow Jones Industrial Average is calculated from the weighted trade prices of 30 companies and then asking "Can I use the prices of those 30 companies to calculate what the DJIA was in 1950?" All of the companies that have been part of the DJIA, and all of the weights that have been used, are documented, but the many sites that publish the DJIA never talk about them. -- Steve Allen <[email protected]> WGS-84 (GPS) UCO/Lick Observatory--ISB 260 Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m _______________________________________________ LEAPSECS mailing list [email protected] https://pairlist6.pair.net/mailman/listinfo/leapsecs
