Next: Equations of condition Up: Extinction and transformation Previous: Extinction and transformation . Bias can also be introduced by improper fitting procedures. For example, the reduction program known as SNOPY, used for many years at La Silla and also at La Palma, uses a simple iterative technique in which some subsets of the parameters are solved for, while others are held fixed; then the ones last solved for are held fixed, while the ones previously fixed are redetermined. ...

... 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. ...
