Use these to check the details of the OH emission lines in your wavelength region of interest. The spectra were wavelength calibrated using this table of OH wavelengths. Please be aware that each spectrum is not shown to the same scale. The OH lines in the H window are much stronger than in K, and those in K are stronger than those in the J band. The spectra are not corrected for atmospheric transmission.
Wavelengths are in vacuo.
The CSO taumeter read approximately 0.05 while the data were obtained. This corresponds to an H 2 O column of 1mm, a good night on Mauna Kea. Click on any of the three spectra below to see a larger scale plot of the same data. Approximate airmass is given in brackets.
