The time coordinates must be used in view of the orbital motion of the Earth. The right ascension α is counted counterclockwise (to the east) from the vernal equinox point. The hour angle t is counted clockwise from the south point; S is the sidereal . These quantities are generally expressed in hours. The azimuth is counted clockwise from the south point from 0◦ to 360◦ . The coordinates are transformed by the formulas sin δ = sin ϕ · cos ζ − cosϕ · sin ζ · cosA, sin A · sin ζ , cos δ cos ϕ · cosζ + sin ϕ · sin ζ · cosA cos t = .

1998). 01(%), respectively. 4 (μm) is about an order of magnitude greater than for the visible region (Hapke 1963, 1971). For the longer wavelength region, the radiation of the Moon becomes similar to thermal radiation with a temperature of about 400 (K) (Fig. 13) (Moroz 1965; Wattson and Danielson 1965; Leikin and Shvidkovskaya 1972). 8m ) – possess appreciable brightness. The spectral energy distributions for the planets are shown in Fig. 14. The magnitudes as functions of the phase angle Φ are determined by the M¨uller empirical formulas (Abalakin 1979).

46)2 (K) . Here, the wavelength λ is expressed in (μm). The solar flux is given by Sλ = π Re ρe 2 · B(λ, T) (erg · cm−2 · s−1 · ster−1 ) . 43879(cm · K). For practical use there are the following formulas: 20 1 The Radiating Atmosphere and Space Sλ = Sλ = Sλ = 8100 λ5 8100 λ5 4100 λ5 · F(λT) (erg · cm−2 · s−1 · μm−1 ), · F(λT) 10−4(W · cm−2 · μm−1 ), · F(λT) 1012(photon · cm−2 · c−1 · nm−1 ) where the multiplier F(λT) follows from Planck’s formula. 07 · 1014 (photon· cm−2 · s−1 · nm−1 ) = 1390 (erg · cm−2 · s−1 · nm−1 ).
