We show some results about the tolerances on the pointing angle of the sect
ions of the LMT (GTM) in R-2 and R-3, by means of an analysis of the inclin
ation range, energy concentration within the Airy disk, spot diagrams and c
austic surface of rays and normals produced with misalignment in all segmen
ts of The Large Millimeter Telescope, (LMT). All the analysis is done on th
e focal plane.
