Abstract: EMIR, the near-infrared camera-spectrograph operating in the wavelength range 0.9–2.5μm, is being commissioned at the Nasmyth focus of the Gran Telescopio CANARIAS. An associated data reduction pipeline, PyEmir, is being developed in Python with the aim of helping astronomers to reduce the corresponding data. This work shows how the simultaneous correction of geometric distortions and wavelength calibration leads to better spectral resolution than when both operations are carried out separately.
