Calculate values by means of a nth degree polynomial from
user-supplied constants (for example from a lamp calibration certificate).
Usage
FEL_spectrum(w.length, k = photobiology::FEL.BN.9101.165, fill = NA_real_)
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).
Arguments
w.length
numeric vector of wavelengths (nm) for output
k
a numeric vector with n constants for the function
fill
if NA, no extrapolation is done, and NA is returned for
wavelengths outside the range 250 nm to 900 nm. If NULL then the tails are
deleted. If 0 then the tails are set to zero, etc. NA is default.
