Abstract
The Large Millimeter Telescope relies on an active primary surface to achieve its specified surface accuracy. The active primary has two functions: (1) it provides a means to correct the surface for gravitational deformations with changing elevation; and (2) it provides a capability to improve the shape of the surface in real time due to transient effects of thermal gradients within the structure. At LMT, our development work has addressed both problems and in this paper we describe the derivation of the gravity deformation model and the schemes developed to measure and improve the antenna surface during regular scientific observations.
