                                   NOTES

   Array elements 14 and 15 are set to zero
   All array elements with blank fields are set to zero
   All angles (latitudes, longitudes, azimuths, etc.) are entered in packed
 	degrees/ minutes/ seconds (DDDMMMSSS.SS) format

   The following notes apply to the Space Oblique Mercator A projection.

      A portion of Landsat rows 1 and 2 may also be seen as parts of rows
   246 or 247.  To place these locations at rows 246 or 247, set the end of
   path flag (parameter 11) to 1--end of path.  This flag defaults to zero.

      When Landsat-1,2,3 orbits are being used, use the following values
   for the specified parameters:

      Parameter 4   099005031.2
      Parameter 5   128.87 degrees - (360/251 * path number) in packed
		    DMS format
      Parameter 9   103.2669323
      Parameter 10  0.5201613

      When Landsat-4,5 orbits are being used, use the following values
   for the specified parameters:

      Parameter 4   098012000.0
      Parameter 5   129.30 degrees - (360/233 * path number) in packed
		    DMS format
      Parameter 9   98.884119
      Parameter 10  0.5201613
