Testing Giano spectral stability

摘要

Giano is a high resolution (R'50,000) infrared spectrograph with a near-complete coverage of the 0.95-2.5 micronswavelengths range. It was assembled in Arcetri-INAF (Florence) and is beeing shipped to the its final destinationat the TNG telescope (La Palma)We present our measurements of internal wavelength stability of Giano spectra. We are using a new approachwhich gives both the wavelength and field tilts. We also show the comparison with the usual mono-dimensionalapproach.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
