He also mentioned that the "second edition" is a second printing of the first edition with some mistakes, but not all, corrected. To know if you have the second printing, have a look at page 183, to the lower right of the figure. If the equation reads 0 deg < M < e < v < 180 d, you have the first printing. If there is a capital E it is the second printing. (Please note that I have replaced the degree sign by "d".) The other errors: p. 89: as mentioned in the reference mail (sin instead of cos). p. 139: in the formula for pi, in the lower half of the page, replace 0.71953 by 1.71953. p. 229, 3rd line from bottom, read "put equal to 3Qt". This does not affect the program listing on the next page. p. 286, last line, replace "II" by "III". p. 312, example 45 a. There are 4 mistakes. read "SIGMA r = -16590875" ^^^^ read "DELTA = 385 000.56 - 16590.875 = 368 409.7 km" ^^^^^ ^^^ in the equation for pi, 3rd line from the bottom, read "368409.7" instead of "368408.4" p. 317, 4th line from bottom, read "(46.1)" instead of "(46.5)". p. 356, upper half of the page, read "JDE = 2450 708.4759" ^ and 4 lines further down "JDE = 2450 708.2835" ^ p. 359, for the semidiameter of Saturn read "83.33" instead of "83.83". p. 393, line 3, read "5.559" instead of "3.559". Let's hope that's all.
