C++ (Cpp) calcSunApparentLong示例

示例#1

文件： sunrise.cpp 项目： mce35/agocontrol

double calcSunDeclination(double t)
{
    double e = calcObliquityCorrection(t);
    double lambda = calcSunApparentLong(t);

    double sint = sin(degToRad(e)) * sin(degToRad(lambda));
    double theta = radToDeg(asin(sint));
    return theta; // in degrees
}

文件： sunzenith.c 项目： rnjacobs/dockapps

/*  Purpose: calculate the declination of the sun (degrees) */
double calcSunDeclination(double t) {
    return rad2deg(asin(sin(deg2rad(calcObliquityCorrection(t))) *
                         sin(deg2rad(calcSunApparentLong(t)))));
}
