... 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 rotation of the stellar component of galaxy is obtained from the compilation of internal stellar kinematics . The rotation of the gaseous component is given in the parameter vmaxg , and the stellar velocity dispersion in vdis . For disk-like galaxies (eg. mostly disks of spiral), the apparent rotation may be converted into the true (physical) rotation using the inclination given in the parameter incl . HyperLeda .
