Abstract:
Results from a pre-launch radiometric calibration of the 21-channel HIRDLS instrument will be presented. These data were obtained during the pre-launch calibration of HIRDLS at Oxford University (Fall 2002). Two external blackbody cavities were used to generate temperatures between ∼90 K to ∼320 K. These blackbodies were located, along with HIRDLS, inside a large vacuum chamber. Data were taken at three different focal-plane temperatures (61 K, 66 K, and 71 K). This paper will cover a variety of details; such as, data-taking procedures, analysis methodology, and the resulting linearity analyses.
