We have introduced a new cosmic shear statistic which decomposes the shear correlation into E- and B-modes on a finite angular interval. The new function is calculated by integrating the shear two-point correlation function with a filter function. The filter function fulfills the E-/B-mode decomposition constraints given in Schneider & Kilbinger (2007).

To compile and run the code:
The package fftw3 has to be installed. If it is not in a standard directory, fftw3.h is looked for in $(FFTW)/include and libfftw3.a in $(FFTW)/lib. Change the variable `FFTW' in the Makefile accordingly. You can download fftw3 from http://www.fftw.org.
The program produces two files, Tpm containing the filter functions T+ and T-, and REB containing the shear functions RE and RB.
