Calculate deuterim lamp output spectrum from fitted constants

Description

Calculate values by means of a nth degree polynomial from user-supplied constants (for example from a lamp calibartion certificate).

Usage

1
D2_spectrum(w.length, k = D2.UV653, fill = NULL)

Arguments

w.length

numeric vector of wavelengths (nm) for output

k

a numeric vector with n constants for the polynomial

fill

if NA, no extrapolation is done, and NA is returned for wavelengths outside the range of the input. If NULL then the tails are deleted. If 0 then the tails are set to zero, etc. NULL is default.

Value

a dataframe with four numeric vectors with wavelength values (w.length), energy and photon irradiance (s.e.irrad, s.q.irrad) depending on the argument passed to unit.out (s.irrad).

Note

This is function is valid for wavelengths in the range 180 nm to 495 nm, for wavelengths outside this range NAs are returned.
