Calling Sequence

---

  ans = getsalb2(bidref,emu,smu,g,holes,p,b0,theta)

Inputs

---

  bidref - The bi-directional reflectance.
  emu - Cosine of the emission angle.
  smu - Cosine of the incidence angle.
  g - Phase angle, in radians.
  holes - Compaction parameter value (1981 formalism).
  p - Value of the single particle phase function.
  theta - Surface roughness value. (radians)

Optional Input Parameters

---

  None.

Keyword Parameters

---

  H93 - Flag, if set, uses the 1993 version of Hapke's approximation to the
            Chandresekar H function. The 1993 version is more accurate but
            considerably slower to compute.

Outputs

---

  returns the single scattering albedo.

Common Blocks

---

  None.

Side Effects

---

  None.

Restrictions

---

  This works on scalar input only.
