| Lambda |
lambda refers to the wavelength of a photon, usually in [?, and E refers to its energy, usually in [keV]. For grating data, because the RMF is almost diagonal, these also refer to the detector bin. Low-resolution spectra are placed in channel bins, whose boundaries are mapped to approximate ranges of photon energies via a gain map.

| Lambda |
The 11th letter of the Greek alphabet. Lambda is used as the symbol for wavelength in lightwave systems. Fiber optic systems use multiple wavelengths of light through dense wavelength division multiplexing (DWDM). Each range of wavelength appears in a "window" roughly corresponding to a color in the visible light spectrum.
