Hi John, Sorry for taking a few days to reply myself. Yes, that's what I'm looking for. A co-worker here at Cornell finally found a site on the web that let you look this up. I don't offhand remember the value we got for the Cornell Campus but could you tell me what value your book has for 42.48N 76.47W? Probably the table in your book simply uses one of the approximation formulas (given how coarse the data is and the fact that you said it is only for latitude). Thanks!
