Cosmology data from CFHTLenS: Benjamin et al 2013

===================
NofZ files:
The n(z) histograms are in PMC format #hist [z, n(z)]
Download files: http://www.roe.ac.uk/~heymans/stat_classification/2bintomo_2012/NofZ_files_2_broad_bin
The PZ_full is taken from catalogues and normalised such that the sum(Pz) = 1 for each galaxy. The final n(z) in the histogram file is the weighted sum of the P(z) using the lensfit weights for the W1234 pass-fields
==================
Xi_pm files
Format: theta, xi, p/m, bina_binb
Download files: http://www.roe.ac.uk/~heymans/stat_classification/2bintomo_2012/tomo.dat
Example: line 1:
1.338921 8.7628221E-05 p low_low
Correlating galaxies between the low z and low z bin we measure
xi_p(theta=1.338921) = 8.7628221E-05
=================
Covariance Matrices
These files are in PMC format: theta changes the most quickly, then p/m, then redshift in the order 1,1 (low_low): 1,2 (low_high): 2,2 (high_high)
Download file: http://www.roe.ac.uk/~heymans/stat_classification/2bintomo_2012/cov.dat
Note that the Hartlap/Anderson correction has *not* been applied to this covariance matrix: this is an input to PMC and should be calculated from
alpha = (n-p-2)/(n-1).
For 8 angular bins for the 2-bin tomography results we'll have
p = 8 (theta) x 3 (tomo) x 2 (xi+/-) = 48
n = 184
alpha = (n-p-2)/(n-1) = 0.73224
