      MAG2GEO()

Purpose

---

    Convert from geomagnetic to geographic coordinates

Explanation

---

 
    Converts from GEOMAGNETIC (latitude,longitude) to GEOGRAPHIC (latitude,
    longitude). (altitude remains the same)

Calling Sequence

---

      gcoord=mag2geo(mcoord)

Input

---

      mcoord = a 2-element array of magnetic [latitude,longitude], or an
                array [2,n] of n such coordinates.

Keyword Inputs

---

Output

---

      a 2-element array of geographic [latitude,longitude], or an array [2,n]
            of n such coordinates

Common Blocks
