The projected and redshift-space galaxy 2PCFs and the corresponding covariance matrices for SDSS DR7 volume-limited luminosity threshold samples using 400 jackknife subsamples: (wpxi_* for measurements and wpxicov_* for covariance matrices) 
The columns for wpxi_* are: 
#1. rp or s, 12 logarithmic bins in units of Mpc/h, starting from 0.1 Mpc/h, with a bin size of \Delta\log(rp)=0.2 
#2. wp(rp), integrated along the line of sight to 40Mpc/h 
#3. xi_0(s), Monopole moment 
#4. xi_2(s), Quadrupole moment 
#5. xi_4(s), Hexadecapole moment 
The covariance matrix for the measurements of xi=[wp, xi_0, xi_2, xi_4] in each wpxicov_* file can be read as a two-dimentional array of 48 rows X 48 columns, i.e. cov(48,48). 

For convenience, we also provide the measurements and errors for wp only
The columns are: 
#1. rp 
#2. wp(rp), integrated along the line of sight to 40Mpc/h. 
#3. Error on wp, measured from 400 jackknife samples.
