  • Table 1

    Data from F 4

    10.17182/hepdata.15557.v1/t1

    Data read from graph.. Additional overall systematic error 25%.

    Data from F 6

    10.17182/hepdata.15557.v1/t2

    Data read from graph.. Additional overall systematic error 25%.. The Q**2 approx 0 datum is deduced from the earlier TASSO...
