+""" This test was benchmarked against the an ED-solver that is 
+independent of TRIQS and was supplied by Wei Wu (May 2016). 
+Due to noise in the Monte Carlo data, it is not possible to 
+automatically check whether the CTHYB solver gives the same result
+as the ED code.
+Thus, this test just checks against the CTHYB data it produced when
+the test was created, which were checked against the ED result.
+The data from the ED solver can be found in the file 
+complex_Gtau_ED.bench.h5 for future reference.
