1# @(#)solar89 1.3 2 3# Apparent noon times below are for Riyadh; they're a bit off for other places. 4# Times were computed using a formula provided by the U. S. Naval Observatory: 5# eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l) 6# -12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l) 7# + 19.3 * cos(3 * l); 8# where l is the "mean longitude of the Sun" given by 9# l = 279.642 degrees + 0.985647 * d 10# and d is the interval in days from January 0, 0 hours Universal Time 11# (equaling the day of the year plus the fraction of a day from zero hours). 12# The accuracy of the formula is plus or minus three seconds. 13# 14# Rounding to the nearest five seconds results in fewer than 15# 256 different "time types"--a limit that's faced because time types are 16# stored on disk as unsigned chars. 17 18# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 19Rule sol89 1989 only -
