PI+ PI+ correlations. The correlation function is parametrized as follows R = 1 + CONST(NAME=BEC-LAM)*EXP(-CONST(NAME=BEC-R)**2*MQ**2), where MQ**2 = M(pi1 + pi2)**2 - 4*M(pi)**2.

PI- PI- correlations. The correlation function is parametrized as follows R = 1 + CONST(NAME=BEC-LAM)*EXP(-CONST(NAME=BEC-R)**2*MQ**2), where MQ**2 = M(pi1 + pi2)**2 - 4*M(pi)**N = RE.
