# Elastic and proton-dissociative photoproduction of J/psi mesons at HERA
#  [arXiv:1304.5162]
#
# In this document, the differential cross sections as a function of t
#  are given for the low energy dataset together with a decomposition
#  of the error matrix. 
#
# The rows of this table correspond to the data rows of table 6
#  of the publication [arXiv:1304.5162].
#
# The table has 8 rows, corresponding to 8 cross section
#  measurements. Each row has 19 columns, as explained in the following
# 
# Version 1, date 20.6.2013
#
# Column 1-8: differential cross section measurement
# column    comment
# =====================
#  1 (n)    row number
#  2 (pd)   pd=0 if the reaction is elastic, pd=1 if proton dissociative
#  3 (|tmin|) lower bound on the modulus of the momentum transfer [GeV^2]
#  4 (|tmax|) upper bound on the modulus of the momentum transfer [GeV^2]
#  5 (|tavg|) average modulus of the momentum transfer [GeV^2]
#  6 (PhiT) transverse polarized photon flux
#  7 (sigm) measured differential cross section [nanobarn/GeV^2]
#  8 (dsig) total uncertainty on the differential cross section [nanobarn/GeV^2]
#
# Column 9-19: error sources
# column    comment
# ===================
#  9 (dunc) uncorrelated uncertainty [nanobarn/GeV^2]
# 10 (dc1)  1st correlated uncertainty from data combination [nanobarn/GeV^2]
# 11 (dc2)  2nd correlated uncertainty from data combination [nanobarn/GeV^2]
# 12 (rnor) normalisation uncertainty from trigger, track and psi(2S) [percent]
# 13 (rlle) luminosity uncertainty for this (low energy) data set [percent]
# 14 (rlar) LAr tagging uncertainty [percent]
# 15 (rplu) PLUG tagging uncertainty [percent]
# 16 (rfts) FTS tagging uncertainty [percent]
# 17 (rmod) model uncertainty [percent]
# 18 (rq2)  Q^2 dependence uncertainty [percent]
# 19 (rec)  empty calorimeter cut uncertainty [percent]
#
# Note 1: the uncertainties from col=8 to col=11 are absolute uncertainties
#  measured in nanobarn/GeV^2, whereas the uncertainties from col=12 to col=19
#  are given in percent, relative to col=7.
#
# Note 2: when adding all uncertainty sources corresponding col=9 up to
#  col=19 quadratically, the result is equal to the total uncertainty
#  given in col=8 (sanity check).
#
# Note 3: the uncertainties given in col=10 up to col=19 are correlated
#  across the rows of the table, i.e. they contribute to the
#  off-diagonals of the covariance matrix. In contrast, the
#  uncertainties given in col=9 are uncorrelated, so they contribute only
#  to the diagonals of the covariance matrix.
