Notes. For some representative diffraction orders of the echelle spectrograph, we provide the central wavelength (CW) in the middle of the order, the start and end wavelength of the FSR, and the start and end wavelength of the total (extracted) spectral range (TSR). Additionally, the spectral size of a physical detector pixel (resolution bin) located in the center of the order is given.
