| apodizatiion |
|
In general, it is any procedure used to damp out oscillations in the wings of the Instrument Line Shape function (the impulse response). It can either be applied deliberately during data analysis or it may occur naturally (self-apodizatiion). Apodization is always inverse to spectral resolution. |
| Apogee |
|
Presuming a non-centered and/or non-circular orbit, it is the point in the orbit when the orbiter and the orbitee are farthest apart. |
