First light with NEWFIRM

摘要

Newfirm, the widefield infrared camera for the NOAO 4-m telescopes, saw first light in February 2007 and is now in service as a general user instrument. Previous papers have described it conceptually and presented design details. We discuss experience gained from assembly, laboratory testing, and on-sky commissioning. We present final system performance characteristics and summarize science use in its the first semester of general availability. NEWFIRM has met its requirement to provide a high efficiency observing system, optimized end-to-end for survey science.
