length	length of fuzz_smear ( Read )
j_decay	direction of time ( Read )

Discription:

The sink fuzzed propagator is calculated by extending the path of the input propagator and is sum of the two contributions as follows:
In the positive mu direction ___3 fuzz \ + + + psi (x) = ) U (x-mu) U (x-2mu)... U (x-length mu) psi(x-length mu)

/ mu mu mu

mu = 1 In the negative mu direction ___3 fuzz \ psi (x) = ) U (x) U (x+mu) U (x+2mu)... U (x+(length-1)mu) psi(x+length mu)

/ mu mu mu mu

mu = 1

                                             fuzz

Where U defined in the the above equations is U mu mu length is an input parameter that describes the size of the smearing.

This code assumes that the gauge field has been fuzzed externally.

(Documentation from Peter Boyle's Fortran code).

For smearing at the source the input is a local source.
