... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

The vopt parameter is computed from the optical measurements in the compilation of redshifts by rejecting outliers and measurements marked for their bad quality and computing a weighted average of the remaining measurements. ... The optical measurements are first selected and converted to a uniform system as: vop = cz + zeropoint(iref) , where cz is the compiled value and zeropoint(iref) a zero-point correction for the reference iref . ... Finally, the individual corrected measurements are combined. ...
