All SOHO/CDS data will be stored and archived in FITS files with binary table
extensions and optional multidimensional arrays.  The format of a CDS FITS 
binary table file can be described as having three parts:  

(1) The main FITS header.  This will describe the observation as a whole.  
Definitions of the main header keywords are registered under NSSD0229 
(SOHO/CDS FITS File Description).  There will be no data array associated with 
the main header.

(2) The FITS header for the binary table.  Except for those records peculiar
to the FITS structure, this will replicate the information in the main header.
It will also describe the columns of the binary table.  Definitions of these 
header keywords are registered under NSSD0229.

(3) The body of the binary table.  This will contain one complete raster.  
Every data window will be stored in a separate column.  Additional columns 
will be used to store the data about the individual exposures (e.g., time,
pointing, etc.).

Each SOHO/CDS FITS data file will be accompanied by a catalog object.

The catalog object will be in PVL format and will contain a single FITS_HEADER 
PVL Object.

Statements within the FITS_HEADER PVL Object are the Keywords and values
which appear in the FITS Header in SOHO/CDS FITS data files.

The meaning of each possible Keyword is given by the 'included' data entity 
dictionaries registered under NSSD0229.
