This AOT can make use of both the `single pointing' and the `raster scan' observation modes of the satellite (See ISO Observer's manual for definitions). It is very flexible and allows to perform up to 64 observations within a single AOT.
An observation is a set of frames recorded in a given optical configuration of the camera. A raster scan stands for one observation, it is performed in one optical configuration. Within a single AOT, the center of the rasters and the single pointings have the same celestial coordinates, and the raster parameters are entered only once (the observer may decide to repeat the raster with different PFOVs, but combining these data may produce strange results).
For all the filters for which a dashed line is shown in the figures
to , the sensitivity of single pointing
observations can be strongly limited by the flat-field accuracy.
Micro-scanning with a raster scan or using beam-switching
(CAM03) is then recommended.
The total time 
spent for an observation is the sum
of the 3 terms:
which are described in sections ,
and for a single pointing,
and , and
for a raster.
