The basic integration step (dump) is 1 second. Transmitting a full spectrum
is impossible at such a rate: there are too many channels... Available
integration times usually range from 15 to 240 seconds, although a few
specific observing procedures have a shorter duration (5 seconds). However,
the correlator produces two types of data:
- the Time data, which is a frequency averaged data computed every
second. Each unit produces its time data, by averaging the results of an
integration step over a user-defined frequency band (to be selected
within the IF band of the unit, of course). This data is also called the
``Continuum'' data.
- the Spectral data, i.e. the time averaged spectrum for the whole
integration. This data is also called the ``Line'' data.
