Algorithm

read input parameters
find angles of the SIAM corresponding to current instrument

STATT:
calculate pointing of the star-tracker for ref attitude

SRCinFOV:
calculate FOV positions of 5 test sources

intended FOV positions:
add offsets (ry,rz) to FOV positions of 5 test sources

minimize distance of "intended FOV positions" from SRCinFOV positions
   by of iteration SIAM angles and re-calculating STATT and SRCinFOV.

print resulting angles
