   Specifications of BINDISP_SUMMARY  format version of 2002.12.12
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


  A file in BINDISP_SUMMARY format keeps information extracted from 
the headers of the set of files of site position variations in 
BINDISP format. Information in BINDISP_SUMMARY files is in ASCII form 
and it is designated for visual inspection and for parsing software 
which can use this information without necessity read all files.

  A file in BINDISP_SUMMARY format consists of records of variable 
length in ASCII coding. Lines which starts from # are considered as 
comments and ignored.
  
  A file in BINDISP_SUMMARY has the table of the format identifier: 
which is the first record of a file and data records. The label of
format identifier is:

BINDISP Summary file. Format version of 2002.12.12

  Date records are of one of the following types which follow in this
order:

LAST_UPDATE: 
MIN_EPOCH: 
MAX_EPOCH: 
L_STA:

STA:      

  LAST_UPDATE record keeps the date of BINDISP_SUMMARY creation.

                        YYYY.MM.FF-hh:mm:ss format

  MIN_EPOCH record keeps the earliest time epoch among of all files 
of site position variations.

  MAX_EPOCH record keeps the latest time epoch among of all files 
of site position variations.

                        YYYY.MM.FF-hh:mm:ss.sss format
  
  L_STA record keeps the number of files of file position variations.
Since each file of position variations keep data for only one site,
this number is the as the number of sites.

Field    1:6   A6    -- record identifier: L_STA
field    7:7   a1    -- filler: blank
Field    8:16  I9    -- The number of files (sites)

  L_DSP record keeps the total number of points in all files of site
position variations combined.

Field    1:6   A6    -- record identifier: L_DSP
field    7:7   a1    -- filler: blank
Field    8:16  I9    -- MJD at midnight of the latest date

  STA records keeps information obtained from the header of the site
position variations files. The number of STA records is defined in 
the L_STA record.
