bbr

Description

The bbr() function computes the black-body curve corresponding to the specified temperature, for the given wavelength(s).

Arguments and Return Values

Arguments: a wavelengths array and an equally sized temperature array.

Return Value: an array of equal size to inputs containing black body radiance.

Usage

Syntax: bbr(wavelength, temp)

The bbr() function is a binary operator function (see bop).

Wavelengths are assumed to be in units of wavenumber (1/cm).

The bbr() function returns a DOUBLE.
