README file for Limber_code_nl_fe_fast_weiner_publc/


1) Makefile:

You should edit the Makefile so that the code compiles.
It assumes that the CAMB diretory is compiled appropriately. 

2) camb/ 

This is the directory which contains the camb code that were downloaded 
off http://camb.info a while ago. 
This version of camb works perfectly fine with the limber code we provides, but 
one should feel free to change the version of camb.

3) run.sh : 

The script that will compile the files and runs the code with sample inputs.

4) The routines: 

 a) lrg_pk.f90 : contains auxillary routines mostly
 b) lrg_2dCl.f90: the main code which computes all the coefficients
 c) cal_likelihood.f90: the driver of the code, which reads in particular files: 
    i) wmap_5yr: the parameter files  (cosmological parameters) 

    ii) rinverse.dat: this file is currently not used, but one can apply this through read_rk() function (in lrg_2dCl.f90). This basically documents the scale dependent correlation 
coeffients between the real velocity fields and the reconstructed velocity fields. 

    iii)bdndz_ADEPT: the bias*dn/dz file (n here being the number of galaxies), thus dn/dz means the number of galaxies in certain dz (redshift) bins. 
I only use the 6th column of the file (see lrg_rdzdist() function in lrg_2dCl.f90) 

5) Outputs: 

a) cl_inside.dat: This is the cls that are calculated for a particular list of \ells, but one can change that list easily. 

b) output file (onto the screen if we don't redirect it) that contains mostly 
checkpoint-type information.
