DESCRIPTION = "This file serves as an index to the image data in FILE_15.     
  This file is used by several VICAR and GIPS programs to directly access     
  portions of the BIDR swath without having to read the entire image.         
                                                                              
  Index files are in VICAR/IBIS format. They consist of an ASCII header,      
  followed by data blocks.  The header consists of a series of blank-delimited
  ASCII strings, each in the format 'keyword=value'.  If 'value' contains     
  blanks, it is enclosed in single quotes.                                    
                                                                              
  The first keyword is LBLSIZE, whose value, usually 512, is the length of the
  header, in bytes.  Other important header keywords are NS, the length of    
  each data block (also usually 512 bytes), NL, the number of data            
  blocks, ORBIT, the BIDR orbit number, and REF_MERIDIAN, the reference       
  meridian of the BIDR's sinusoidal projection.  The remainder of the header  
  block is filled with NULs.                                                  
                                                                              
  The header is followed by a single data block which starts with a 4-byte    
  integer field whose value is the number of data blocks, nblk, in the        
  original BIDR. The integer is written in VAX binary format.                 
                                                                              
  The remainder of the index file consists of 10 groups of data blocks. Each  
  group consists of nblk 4-byte fields, and the last block of each group is   
  padded with NUL bytes to a multiple of the block length, NS.  The total     
  number of data blocks is therefore 10*ceil(4*nblk/NS)+1, where the ceil     
  function returns the smallest integer that is not less than its argument.   
                                                                              
  The ten sets of data blocks contain information about the nblk BIDR image   
  data blocks.  Fields marked (I) contain 4-byte VAX signed integers, while   
  those marked (F) contain 4-byte single-precision VAX floats.
