This directory contains 4 subdirectories each of which contains 100 orbits of UCLA corrected pulse time data files, 1 file per orbit. The files are in the original IBM-360 binary representation. There is software provided in the SOFTWARE directory which will convert these files to ASCII on either a Sun (Unix) or a VAX (VMS) system. For a description of the dataset anomaly refer to the file /DATA/AANOMALY.TXT.
