Path: SC/Sensor
% Converts focal plane coordinates into right ascension/declination of the targets.
If no outputs are specified it will create a 3D plot of the
unit vectors for the inputs. In the focal plane the vectors
x = [0;1;0] and y = [sin(decC);0;-cos(decC)] define the sysstem
of coordinates that is used to measure the plate and which is
oriented North-SOutha and East-West.

Form:
[ra, dec] = FP2RADec( rAC, decC, x, y, f )
--------------------------------------------------------------------------
------
Inputs
------
rAC (1,1) Right ascension of the camera axis (rad)
decC (1,1) Declination of the camera axis (rad)
x (n) X coordinate
y (n) Y Coordinate
f (1,1) Focal length
-------
Outputs
-------
rA (n) Right ascension ( 0 to 2*pi) (rad)
dec (n) Declination (rad)
