ALOHA 1.55μm Implementation on the CHARA Telescope Array: On-Sky Sensitivity Tests
Abstract
We intend to implement the ALOHA at 1.55μm up-conversion interferometer on the CHARA Array. After a full laboratory investigation, a sensitivity evaluation is conducted on several stars using a single interferometric arm in a photometric mode. The on-sky photometric results allows us to calibrate a numerical simulation of the interferometric configuration, and to predict the future performance of ALOHA at 1.55μm as a function of the seeing conditions.
