NOEMA, previously Plateau de Bure Interferometer (PdBI), has seen
continous improvements since its start, with more than five
generations of receivers and correlators along with the development of
atmospheric phase correction techniques. Given the nature of the CLIC
data file, this was associated with many, sometimes small, changes of
the data format. CLIC is designed so that its latest version can read
and process any version of the data format and map it in memory to the
latest data format. Data of any date can hence be processed with the
latest CLIC version. Note that writing the data is always done with
the latest data format (except if one updates an observation,
i.e. modify an existing .hpb file). In practice, the data format used
the section length (stored in the file) to see whether there were
extensions to a section. With the introduction of CLASSIC , a version
number is stored with the observation.
