For a quick second when I was writing 607/606 and 587/586 I thought something was not right, but the thought left without my discovering the error in that comment. However, the years in the tables are all right, I think. I am no longer confident when you are around; you have quite an eye to discover any kind of mistake.
I just checked the city I chose for my calculations. It is only 40 miles south af Al Hillah.
Before Ann catches another error, I just want to note that I misspelled "descending" in the headings of table
Thanks again for the corrections.
