If your browser cannot view GIF files, you may want to save the PostScript (PS) files locally (from directory: wqn\qasure\graphics), and print them on your laserprinter.
The naming convention for the PS files is QWyy_nna.ps where 'a' is a sequential character corresponding to the order of presentation of figures and tables in the memoranda. The PostScript file names are listed below, and are also given in the 1st_read.me file in the graphics sub-directory.
