Oops! Sorry about the banal error, and most grateful for all the comments. Fortunately nothing was carved in stone, and the sign error has now been corrected.
Other points: 1. The incorrect "Equation of Time" has now been relabelled "Standard Time Correction" and it is explained that it is the sum of EOT and the longitude correction 2. I have learnt something about astronomy. However, for the current purpose we will stick with the +180 to -180 convention 3. Printing. You have to print it landscape (not portrait) and you may need to narrow the margins to get December on. We cant see any way round this one. It is explained on the final page. We have now reposted the pages of www.solar-noon.com, and I have sent a further message outlining two outstanding matters concerning the Equation of Time, on which I would welcome views. Many thanks to all Piers Nicholson
