Abstract

The requirements for the Near Infrared Camera (NIRCam) instrument for NASA's James Webb Space Telescope (JWST) designate that the instrument be aligned to within specified wavefront tolerance limits. A sensitivity analysis was performed to determine the best selection of field point locations and wavelengths at which to take measurements to meet the wavefront requirements. This paper presents an overview of this analysis.
