Additional Notes:

  Two diagnostic files are generated for each file during the ingest process.
  The two diagnostics are latitude and longitude sections of the
  image. For each channel (eg. Visible and Infrared) present in the raw file a 
  column is created in the diagnostic files. For sgpgoes8X1, the maximum 
  of diagnostic file per day is 96. For sgpgoes8visX1, the maximum of
  diagnostic file per day varies from month to month since 
  sgpgoes8visX1.a1 data are processed only for the time when 
  Central Facility is sunlit. The average of diagnostic file for sgpgoes8visX1
  is about 46. The diagnostic file is a compressed ASCII file.

  Diagnostic files can be used to create daily and monthly temporal 
  distribution hovmuller gif files. Web based data viewers use these files to
  provide a quick overview of the conditions, data quality and data 
  availability during a particular time period as depicted by the satellite 
  imagery.

  We have files covering 12/15/94 - present. Beginning on 9/22/97, we are 
  planning to send out the three month's worth of backlog data per day for 
  the next couple of days. We will then send the month's worth of data 
   (~30-31 files) at the end of each month.
