... 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. ...

Sunspots are cooler features (3800 degrees Kelvin) wandering across the disk of the Sun that have been observed since ancient times. ... Solar activity is directly related to the frequency of sunspots. ... ROTATION: The sun does not rotate as a rigid body. ... The next task is to download a complete time series of images that illustrate how your sunspot is moving due to the sun's rotation. ...
