COMMENT          The pixel index is intended to simplify and expedite data      
COMMENT          retrieval for a user-selected subset of pixels in the CIO.     
COMMENT          There is one row in the index table for each DIRBE pixel       
COMMENT          (resolution 9) observed on this day.  Pixels are listed in     
COMMENT          ascending order.  For each pixel, the pixel index table        
COMMENT          identifies the LAST row number within the corresponding
