I have put the corrected method for finding wall declination on my website (the handout from the NASS conference had significant errors). Go to www.precisionsundials.com/software.htm and download "Wall Declination.doc". It is an MSWord Document. You can also download an MSWorks spreadsheet to assist the calculations called WallDec.wks. I hope this time I've got all the bugs out.
