Description Usage Arguments Value Examples
Given an instrument-specific response function (IRFλ) in units Mass squared Length per squared Time count, the 'integration time' of the calibration measurement in units Length and a vector of center points for the bands that make up the spectral measurement in units of Length this function will return IRFnorm,λ in units of Mass cubed Length per Time count.
The usual case is IRFλ given in J/count
Calculated as:
IRFnorm,λ = t × dλ / IRFλ

irf |
instrument-specific response function (IRFλ), usually with units J/count |
int_time |
The ‘integration time’ (*t*) of a measurement i.e., the time period over which the instrument records light through the measuring apature. Usually seconds. |
wavelengths |
Center points for the bands that make up the spectral measurement (λ) i.e., the wavelength scale. Usually units of nm. |
The normalised IRFλ vector.
