A revised set of temperature-dependent absorption cross sections for ultraviolet (UV) measurements of formaldehyde (H2CO) has been derived from two existing sets of laboratory cross sections, one using a Fourier transform spectrometer (FTS), and one using a grating instrument. This is conducted to satisfy the recommendation of the HITRAN Advisory Committee to provide a dataset with the spectral...

In multivariate calibration by for example ordinary least squares (OLS) multiple regression or by partial least squares regression (PLSR) the predictor ŷ(x) is perfect for the calibration sample itself, in the sense that the regression of observed y on predicted ŷ(x) is y = ŷ(x). Plots of y against ŷ(x) are much used to illustrate how good the calibration is and how well prediction works. Usual...
