[Utah-astronomy] Roger Sinnott's article "A Spreadsheet for Polar Alignment"

Kurt, Do you have a copy of Roger Sinnott's article in the Sept '91 S&T issue "A Spreadsheet for Polar Alignment" pp 299-301? Does it work through the math a little bit? I want to calculate the RA and DEC drift of a star as a function of alt and az polar misalignment, I have the spreadsheet you put together that goes the other way. Cheers David
