TRANSCRIPT
On the right side, the "eye" of the DOASis shown. With this telescope, straylight from the sky is guided by an opticalfiber into the spectrometer inside the observatory.

derived from the elastic wavelength pairwhile the other was derived using the Raman backscatterwavelengths. The shading and error bars denote the statistical uncertainty.
