spct |
an object of class "source_spct". |
w.band.num, w.band.denom |
waveband objects or lists of waveband objects used to compute the numerator(s) and denominator(s) of the ratio(s). The waveband(s) determine the region(s) of the spectrum that are summarized. |
unit.out.num, unit.out.denom |
character Allowed values "energy", and "photon", or its alias "quantum". |
quantity |
character string One of "total", "average" or "mean". |
wb.trim |
logical if TRUE wavebands crossing spectral data boundaries are trimmed, if FALSE, they are discarded |
use.cached.mult |
logical indicating whether multiplier values should be cached between calls |
use.hinges |
logical Flag indicating whether to insert "hinges" into the spectral data before integration so as to reduce interpolation errors at the boundaries of the wavebands. |
naming |
character one of "long", "default", "short" or "none". Used to select the type of names to assign to returned value. |
