Comparison of wavelength dependent giant star angular diameters with models

We present angular size measurements obtained with the Palomar testbed Interferometer. Our sample includes 82 giant stars, with spectral types between B7 and M7. These objects represent the well studied subset of giant stars observed at PTI.

Keck Interferometer autoaligner : algorithms and techniques

The Keck Interferometer includes an autoalignment system consisting of pop-up targets located at strategic locations along the beam trains of each arm of the instrument along with a sensor and control system. We briefly describe the hardware of the system and then proceed to a description of the two operational modes of the system.
