2.2 Radiation from Terrestrial OI

Terrestrial OI 1304 Å resonance radiation is quite apparent in Figure 4 toward the end of the scan in latitude, and is present to some extent throughout that scan, while terrestrial OI 1356 Å produced by electron-ion recombination is also faintly present. The altitude dependence of this latter mechanism was measured by Brune et al (13). One example of these fundamental ``engineering'' data required to reduce raw data appears in Figure 5. Experiments (e.g., 57) that are planned for above 500 km in altitude should experience no problems due to OI.
