The Zolotarev rational polynomial approximation is used to estimate sign(H_W). The range of the approximation is specified by either "threshold" or "nEngenmode".
The range OUTSIDE the approximation and how contribution from the range is treated. "method"=eigenmode: all eigenmodes in (min,max) are calculated and the sign(H_W) is treated exactly in the range. "method"=ignore: contribution from the range is simply ignored. Note that "min = - max .lt. 0" is an usual cases. Also note that the upper bound of the sign approximation function is not marked up, because it is in general dependent of configurations.
Low-lying eigenmodes (lambda_i, i=1 to "nEigenmode") are identified and the sign approximation formula is applied for the range of x given by "|x| .ge. max_i |lambda_i|". Upper-bound of the range is not marked up.
The number of poles of the sign approximation formula. Positive integer is recommended when "threshold" is given. variable is allowed when "nEigenmode" is given.

link smearing
The base type for defining a link blocking scheme, being the a sum of link paths with common endpoints (those of the original link). The paths are weighted by one or more coefficients.
Block the links using an isotropic APE blocking method. rho0 is the coefficient of the original link. rho1 is the coefficient in front of the sum of six simple staples. rho0 = 0, rho0 = 1 and rho0 = (1 - 6 rho1) are typical examples. Reference: Phys. Lett. B192 163, 1987.
Block the links using an anisotropic APE blocking method. rho0S, rho1SS and rho1ST are coefficients for blocking links in spatial direction: rho0S is the coefficient of the link, rho1SS is that in front of the sum of 4 space-space staples, rho1ST is that in front of the sum of 2 space-time staples. rho0T and rho1TS are coefficients for blocking links in temporal direction: rho0T is the coefficient of the link, rho1TS is the coefficient in front of the sum of 6 space-time staples.
