A procedure for selecting samples to use in multivariate calibration, inspired by a paper by Zemroch, is proposed. The method developed is designed for multicollinear data and is based on cluster analysis. It selects among available spectra the samples to submit to chemical analysis and calibration.
## Abstract Detailed proposals are made for the design of a highβorder FabryβPerot type interference filter in which the transmission bands of the filter are exactly matched to 15 lines of the __R__βbranch of the CO~2~ spectrum near 15 ΞΌ. The striking energy advantages of such an interferometer are
