The quark polarizations for valence up (u_v), valence down (d+dbar) and sea quark (q_s) flavors as a function of x derived from the HERMES inclusive and semi-inclusive asymmetries on the ^3 He and proton targets (Valence decomposition). The first error is statistical and the second one systematic. The values were obtained with the assumption that the sea quark polarization is flavor symmetric. up stat. syst. down stat. syst. sea stat. syst. quarks quarks quarks 0.033 0.215 0.122 0.060 -0.421 0.306 0.113 0.012 0.095 0.039 0.047 0.108 0.094 0.039 -0.354 0.274 0.111 0.109 0.103 0.040 0.065 0.269 0.081 0.055 -0.225 0.266 0.106 -0.055 0.121 0.068 0.087 0.374 0.080 0.062 -0.064 0.297 0.151 -0.215 0.169 0.119 0.119 0.234 0.073 0.050 -0.519 0.320 0.098 0.148 0.236 0.122 0.168 0.270 0.079 0.041 -0.520 0.418 0.114 0.200 0.441 0.148 0.245 0.456 0.093 0.071 0.136 0.630 0.437 -1.108 1.077 0.717 0.342 0.385 0.045 0.026 0.602 0.489 0.264 0.465 0.663 0.064 0.040 -1.127 0.897 0.220 Statistical correlation coefficients rho between the quark polarizations u_v, d_v and sea (q_s) quark flavors in each x-bin.
