Golang ApproxNutation Examples

Example #1

File: nutation_test.go Project: soniakeys/meeus

func TestApproxNutation(t *testing.T) {
	jd := julian.CalendarGregorianToJD(1987, 4, 10)
	Δψ, Δε := nutation.ApproxNutation(jd)
	if math.Abs(Δψ.Sec()+3.788) > .5 {
		t.Fatal(Δψ.Sec())
	}
	if math.Abs(Δε.Sec()-9.443) > .1 {
		t.Fatal(Δε.Sec())
	}
}

Example #2

	jd := julian.CalendarGregorianToJD(1987, 4, 10)
	Δψ, Δε := nutation.ApproxNutation(jd)
	if math.Abs(Δψ*(180/math.Pi)*3600+3.788) > .5 {
		t.Fatal(Δψ * (180 / math.Pi) * 3600)
