experimental noise in the NIR and/or chemical data и overlap and convolution spectr.

[Natuli]

Опять нужна помощь специалистов.. Помогите, пожалуйста, перевести "experimental noise in the NIR and/or chemical data и overlap and convolution" в контексте:
Validation of Analytical Procedures - Water by NIR

The main advantage of the PLS method is that most of the spectral noise is relegated to higher order vectors which are not used in the calibration. A PLS calibration equation is usually more robust than a Multiple Linear Regression (MLR) calibration equation, and allows the detection of spectral outliers. Furthermore, PLS algorithms are useful with small populations of samples that contain some experimental noise in the NIR and/or chemical data. In a
multi-component system, overlap and convolution of individual species spectral
signatures often preclude the use of correlations between absorbance and analyte (water)
concentration.

experimental noise -- шум измерений, шум в экспериментальных данных

overlap and convolution -- наложение и свертка
