This paper presents new trigonometric parallaxes and proper motions for 214 stars. The measurements were made at the US Naval Observatory Flagstaff Station (NOFS) between 1989 and 2017, and the average uncertainty in the parallax values is 0.6 mas. W

The ALADDIN 1024 X 1024 InSb array is now a fact rather than a concept, and the time has come to show test results. In this paper we present lab test data but we have also taken it to the telescope. The development program was a success and the array
