... 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. ...

GrIm II . ... The MC has been modified to change the way GRIM images are stored to disk when FITS format is selected. ... The solution the Grim team has come up with is to internally add a constant of 10000 to every pixel of the 'bias subtracted' grim image which makes it conform to the unsigned 16-bit number standard, in that all pixel values after this addition of 10000 are in the range 0-65535. ...
