Atmospheric Transmission Files

A set of atmospheric transmission files at resolutions comparable to those available with Michelle and T-ReCS is available below. The files were generated using ATRAN. All of them are for the summit of Mauna Kea, a telescope zenith angle of 30 degrees, and 1.6 mm of precipitable H2O.

The file format is: index, wavelength (um), transmission. Spectral sampling is 2 data points per resolution element.

• 7-14um transmission spectra
• R~200
• R~1000
• R~3000
• R~25000
• 16-26um transmission spectra
• R~100
• R~1300
• R~4000
• R~20000
