CAM04 allows to perform a scan of the CVF over a given
wavelength range [
_begin, _end]. The
observer provides a sampling interval 
= an integer
number of steps of the CVF between two points of the scan. The
system determines the ``begin" and the ``end" positions of the
wheels closest to the requested wavelength range limits, and
scans between these positions at intervals. The
Observer can be certain of the exact limits of the scan only if they
have been selected in Tables 
to
that provide for each piece of CVF :
per step
A scan is always performed in the same optical configuration, but,
within a single AOT CAM04 it is possible, always on the same
pointing, to perform several scans, with different optical
configurations (channel, PFOV, wavelength range
[_begin, _end], intervals).
Beam-switching, raster scan, polarimetric observations and FLASH-MODE SW are not supported in CAM04.
The total Observation time for an observation is the sum of three terms :
which are described in sections ,
and .
