Paper Abstract

The fringe detection and tracking system of the Keck Interferometer, Fatcat, has been operational ever since first fringes at Keck, albeit not in full capacity. At present it supports single baseline (Keck-Keck) operations only. We briefly discuss the instrument design from a hardware and controls standpoint. We also show some recent data from the instrument and summarize some performance limits.
