% 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) -------------------------------------------------------------------------- References: Montenbruck, O. and T.
