Example of a calibration image with the cross-dispersed spectral orders. Each band enclosed with dashed lines represents one of the overlapping orders in the spectrograph (order-isolation filters are removed for these operations) that we have used for this work, ranging from 470 (bottom) to 1413 (top) nm. Spectral lines are visible in the data. The central orders have been saturated in the figure to show the weaker ones at the top and the bottom.
