Path: SC/Sensor
% Converts right ascension and declination into focal plane coordinates.
The outputs will only be for valid inputs, i.e. inputs in the visible
hemisphere. 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.
Since version 2.

Inputs
------
rAC (1,1) Right ascension of the camera axis (rad)
decC (1,1) Declination of the camera axis (rad)
rA (n) Right ascension (rad)
dec (n) Declination (rad)
f (1,1) Focal length
-------
Outputs
-------
x (n) X coordinate
y (n) Y Coordinate
k (:) Valid inputs
