description: CERN-SPS. NA4/BCDMS collaboration. Plab 100 - 280 GEV/C. These are data from the BCDMS collaboration on F2 and R=SIG(L)/SIG(T) with a hydrogen target. The statistics are very large (1.8 million events). The ranges of X,Q**2 are 0.06& lt;X& lt;0.8 and 7& lt;Q**2& lt;260 GeV**2. The F2 data show a distinct difference from the data on F2 proton taken by the EMC.. The publication lists values of F2 corresponding to R=0 and R=R(QCD) at each of the four energies, 100, 120, 200 and 280 GeV. As well as the statistical errors also given are 5 factors representing the effects of estimated systematic errors on F2 associated with (1) beam momentum calibration, (2) magnetic field calibration, (3) spectrometer resolution, (4) detector and trigger inefficiencies, and (5) relative normalisation uncertainty of data taken from external and internal targets. This record contains our attempt to merge these data at different energies using the statistical errors as weight factors. The final one-sigma systematic errors given here have been calculated using a prescription from the authors involving calculation of new merged F2 values for each of the systematic errors applied individually, and the combining in quadrature the differences in the new merged F2 values and the original F2. The individual F2 values at each energy are given in separate database records (& lt;a href=http://durpdg.dur.ac.uk/scripts/reacsearch.csh/TESTREAC/red+3021& gt; RED = 3021 & lt;/a& gt;).
PLAB=100 GeV/c. These are the data from the BCDMS Collaboration on F2 and R=SIG(L)/SIG(T) with a hydrogen target. The statistics are very large (1.8 million events).

In the preprint are listed values of F2 corresponding to R=0 and R=R(QCD) at each of the four energies, 100, 120, 200 and 280 GeV. Also listed are 5 systematic errors associated with beam momentum calibration, magnetic field calibration, spectrometer resolution, detector and trigger inefficiencies and relative normalisationuncertainty.. The sytematic error shown in the tables is a result of combining together the 5 individual errors according to a prescription provided by the authors. Themethod involves taking the quadratic sum of the errors from each source..
