Comparison lamp atlas (CuHeNeAr)

The comparison lamp atlas (CuHeNeAr) for the Boller & Chivens spectrograph was recently updated. The report for this update can be found here (download report - Spanish version). 

The spectrum in FITS format for IRAF can be downloaded here. The spectral lines of Cu, He, Ne, and Ar identified in this spectrum can be consulted in the folowing list (download). The list of spurious lines (yellow) from other spectral orders that should not be used during the line identificacition process for calibration can be downloaded here.

The lamp spectrum as acquired (M. Richer 2005) in FITS forma for IRAF can be downloaded here. 

Below, users can find charts for identifying the lines of the spectrograph´s comparison lamp. to veiw each chart in detail o download it, click on the image.
