The first two real arguments indicate the extrema of the |

spectral range in nanometers. |

The nmA wavelength may be greater or less than nmB, |
| 1214 |
|
but they may not be equal, and their ordering matches |
| 1215 |
|
the order of the spectral values. |

Like the spectrum primitive, the wavelength range is specified |

in the first two real arguments, and additional real values are |

This function is fed a wavelenth sample |

and it returns the corresponding spectral intensity. |
