THESE RESULTS ON RE(AMP)/IM(AMP) AND SLOPE FROM EXPERIMENTS WA9 AND N78 HAVE BEEN PRE VIOUSLY PRESENTED IN BURQ ET AL., PL 77B/ 438/78, PL 109B/111/82, PL 109B/124/82,AND ARE IDENTICAL EXCEPT FOR THE PI- P SLOPE PARAMETER FROM WA9 (PL 77B/43/78) WHICH HAS BEEN CHANGED BY -0.5 DUE TO THE INTRODUCTION OF A CORRECTION FOR BREMSSTRAHLING AND OF AN EFFICIENCY CORRECTION AT BIG T VALUES, NEGLECTED IN THE PREVIOUS ANALYSIS. WE PRODUCE ONLY THAT PART OF THE TABLE HERE.
