... In order to disentangle the effects of different climate variables on tree-ring growth rates of different species, and to explore the possibility that more than one species could improve the accuracy of the reconstructions of climate using tree rings, a methodical study of trees in close proximity to the Armagh Observatory climate station was initiated together with Ana Maria Garc?a Su?rez, and continued as part of the latter's PhD thesis with John Butler and Professor Mike Baillie (QUB). ...

... 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. ...

... These are ``quirks'' rather than ``bugs''. Below is a list of quirks. When loading a file and ``Reset Intensity Upon File Load'' is disabled, the intensity range of the previous image will be used. ... When moving between two images (such as when blinking, or when loading a new image), the display system attempts to retain the old image parameters (i.e. zoom box). What is retained are the corners of the zoom box measured in image pixel co-ordinates, not world co-ordinates. ...

Such definition means that our statistics for the number of expected BH X-ray binaries include both transient and persistent systems. ... If this value is 2 M , then, according to our calculations, Galaxy contains some 15 000 to 40 000 of BH X-ray binaries (and some 30 000 to 250 000 of NS X-ray binaries). ...
