I've been working on them further, mostly on the text. The 1960s deserve a level of explication which defies fitting onto the plots, especially things like the earliest use of the term UTC that I have found by Guinot in Bulletin Horaire, and the conversion of LORAN chains to cesium clocks. > Cool work, do I spot another disciple of the cult of Tufte ?

In this context, however, Clive Feather might find it more like the Cult of Skaro. The various national agencies who send reps to ITU-R WP7A and SG7 are preparing their contributions and responses now. The process is far too byzantine for me to follow even in the US, let alone in the national bodies of other countries. -- Steve Allen <[EMAIL PROTECTED]> WGS-84 (GPS) UCO/Lick Observatory Natural Sciences II, Room 165 Lat +36.99855 University of California 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] http://six.pairlist.net/mailman/listinfo/leapsecs
