when I said supplementalShadows.pdf I meant to type appendix-main-appendices.pdf sorry. However my averaging fir 4 years is avtually, now I look at it, in the Excel sheet illustratingshadows.xls specifically the "astroEOT" sheet, however I did the averaging for mid month so as a turnkey it may not help. But do look at that sheet as it is easy to modify. The sheet is orotected, so do ALT-T then P then P again to unprotected it. simon

Let me retry with this account. Hi everyone, I am working onmy Equation of Time plaque for my aluminum cross sundial. All the instructions and graphics and EQT willbe on an 8 ½” diameter ½” aluminum plate. I do not want to use the standard graph found on many sundials butinstead a chart for the whole year, mins and secs, to add or subtract totalcorrection to get watch time. I do nothave much room for detailed instructions. I looked atdifference sources for the chart and would like to verify the most accurate timesto use the four year leap year cycle for a church at 40.1526N, 76.6038W. I have looked at the Solar Noon calculator,Sonne and Shadows-(cannot input decimal degrees?) Are there other sources or spreadsheet programs? I like to conveythat sundials are accurate. I envisionthat a person will wait till the shadow is on a line and the person will knowwhat time it is suppose to be even though this type of sundial may not be designfor precision. I made a quickdrawing. There will be some type of sunimage at the top and a logo at the bottom for the location. The chart in the center is from anotherproject that I did just to see how it would look and if the printing is large enoughto read. I would have to change theinputs to standard time for the whole year. I have also attached a picture of the sundial. I just want toknow if I am using the right times and would appreciate any comments orsuggestions. Thanks very much Ken Clark Elizabethtown,PA
