The index 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 ASCII 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. 1. Running sum of the number of pixel lines of data preceding the start of the image data block (I) 2. Physical BIDR record number containing start of image data block header.
