... 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. ...

... We assume that an instantaneous starburst occured in the region of the Galactic center, with half of the stars (in number) being formed in binaries. The total mass of the stars formed during the starburst was taken to be , as indicated by the Tamblyn & Rieke (1993) analysis. ... In fact, the number of stars in IRS 16 estimated by Tamblyn & Rieke (1993) is uncertain within a factor of 2, but this is actually of no importance as long as we only use relative numbers of different X-ray source species. ...

... Chapter 15. 15.0 Introduction Modeling of Data Given a set of observations, one often wants to condense and summarize the data by fitting it to a "model" that depends on adjustable parameters. Sometimes the model is simply a convenient class of functions, such as polynomials or Gaussians, and the fit supplies the appropriate coefficients. ... The parameters of the model are then adjusted to achieve a minimum in the merit function, yielding best-fit parameters. ... Data are generally not exact. ...
