Instrumentation analysis and data processing for rocketborne LWIR spectrometers : <With application to rocket A18.006-2 of 22 March 1973> /

A liquid-helium-cooled long-wavelength infrared spectrometer was successfully launched on 22 March 1973 from the Poker Flats Research Facility, Alaska. This spectrometer, which employed a circular variable filter (CVF), was developed over a period of five years and provided the first measurements of the infrared spectrum of the upper atmospheric emissions between 7 and 24 micrometers. The data processing proceeded in a step-by-step manner to provide accurate final data with error limits and an understanding of the spectrometer performance. Each step of the data processing is presented in this report which will provide engineers with information on the spectrometer performance and data analysts with the basis for the final assignment of error limits. Similar procedures can also be used for the data reduction of other CVF flights."Optical Physics Laboratory Project CDNA.""ADA020810 (from http://www.dtic.mil).""8 October 1975."Includes bibliographical references (pages 43, 45-46).A liquid-helium-cooled long-wavelength infrared spectrometer was successfully launched on 22 March 1973 from the Poker Flats Research Facility, Alaska.
