Functions for calculating experimental errors on the PDFs, structure
functions and cross sections
For every function given above, 20 additional functions are available
to calculate the experimental error on the function. For example, for
uval00h1ms.f, these error functions are uval00h1mspN.f and uval00h1msmN.f
where N=0,...,9 corresponding to 10 free parameters used in the fit.
To get the experimental error band on positive side, one should add the difference between
uval00h1mspN.f and uval00h1ms.f in quadrature (refer to e.g.
hep-ph/0201195
for more explanations). All error functions and
central functions listed above are available in h1pdf2000_msbar.tar.
Doing "tar -xzvf h1pdf2000_msbar.tar" will provide you the full set of
functions in the MS bar scheme.
Functions for calculating experimental errors on the PDFs, structure
functions and cross sections
For every function given above, 20 additional functions are available
to calculate the experimental error on the function. For example, for
uval00h1di.f, these error functions are uval00h1dipN.f and uval00h1dimN.f
where N=0,...,9 corresponding to 10 free parameters used in the fit.
To get the experimental error band on positive side, one should add the difference between
uval00h1dipN.f and uval00h1di.f in quadrature (refer to e.g.
hep-ph/0201195
for more explanations). All error functions and
central functions listed above are available in h1pdf2000_dis.tar.
Doing "tar -xzvf h1pdf2000_dis.tar" will provide you the full set of
functions in the DIS scheme.
Functions for calculating experimental errors on the PDFs, structure
functions and cross sections
For every function given above, 20 additional functions are available
to calculate the experimental error on the function. For example, for
uval00h1lo.f, these error functions are uval00h1lopN.f and uval00h1lomN.f
where N=0,...,9 corresponding to 10 free parameters used in the fit.
To get the experimental error band on positive side, one should add the difference between
uval00h1lopN.f and uval00h1lo.f in quadrature (refer to e.g.
hep-ph/0201195
for more explanations). All error functions and
central functions listed above are available in h1pdf2000_lo.tar.
Doing "tar -xzvf h1pdf2000_lo.tar" will provide you the full set of
functions in the LO fit.
