Recept:
1.  x,y piksel na CCD, 
    naredimo da se zacne (0,0)
    x=x-1
    y=y-1

2. Normaliziram koordinate:
    w  = FrameWidth
    h  = FrameHeight
    w2 = 0.5 * (w + 1);
    h2 = 0.5 * (h + 1)
    
    x1 = (x - w2) / w
    y1 = (y - h2) / h

3. Izracunaj popravke po formuli

4. Rezultat je 
     x = x + x'
     y = y + y'
   so ravninske koordinate v pikslih, ki pa so popravljene za distorzijo, se 
   preslikajo v ra in dec z TAN projekcijo.
