Arc lamp spectra used for wavelength calibration of LAMOST low-resolution data. Panel (a) presents an exposure of the Hg–Cd arc lamp used for the blue arm, while panel (b) shows an example of the Ne–Ar arc lamp spectrum obtained for the red arm. The red points mark the peaks of the selected emission lines, with their central wavelengths labeled (in units of Å) adjacent to each point.
