Hi Frank, At the start of this thread you wrote: ********** Reference the sundial on the Old Grammar School, Hawkshead, Cumbria, England. The school is a museum, famous as the place of William Wordsworth's education. Over the door is a fine dial dated 1845 with stated co-ordinates, latitude "54 deg. 22 min. 10 sec." and longitude "PL 35 deg. 43 min. 40 sec." **********
In the mean time I found a larger picture of this dial and there is more text as you describe. The part of the text I mean is in the attached picture. A new value I read is: Decl 30 (degrees) 20 (minutes) Now we are able to calculate all the constants of the sundial. I get with ZW2000: Style height 30.19 Angle of substyle 160.1 or 29.9 Hourangle of substyle -35.75 All decimal degrees. I thought: bingo, hourangle of the substyle. But the value you mentioned gives 35.7277.. decimal. Another difference is the text PL Long. I read PI Long.Still not all questions answered but perhaps this gives you another idea how to solve it.
