The level of isolation was determined by estimating the interference by neighboring lines which relies, to a large extent, on the characteristics of the instrument filter system. One candidate ozone line is at 1176.1 cm -1 . The figure below shows simulated emission spectra about this line as would be seen by a high-resolution spectrometer looking at the limb. The filter transmittance was set to unity at 1176.1 cm -1 for this figure. The atmospheric conditions are those of the U.S. 1976 standard atmosphere.
All significant lines are from ozone.
