N. B. Since this Table shows the sun's mean motion during the number of minutes indicated, a slight correction must be made, in order to ascertain his true motion, if very great accuracy is required. The largest possible correction, namely for 59 minutes on the days 81 and 263 (when the sun is in apogee and perigee and is therefore at his slowest and quickest) is on Day 81 minus 5-4516 or 0-0421, and on Day 268 plus the same.
Hence on Day 81 the true sun's journey in 59 m. must be taken as (by the Table, 2' 25"-38-545-) 2' 19-93, or (by the Table, 1-1217-0-0421-) 1-0796; and on Day 263 a4 (2′ 25"-38+5"-45-) 2' 30'-83, or (1-1217+0-0421-) 1-1638.
It is not necessary to frame a Table to meet corrections less than this. Calculation can always be made by taking from the Hour Table (Table XLIX) the true sun's motion in one hour on the day in question, dividing this by 60, and multiplying the result by the number of minutes concerned.
