These observations are aimed at fully charactering FORS1 photometric system (UBVRI zero-points, color-terms and extinction coefficients) for the Tektronix 2048x2048 pixel CCD (24µm px) .

... 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). ...

... This review presents the results of Scenario Machine computations aimed at the population synthesis of different types of binary stars in our Galaxy and another galaxies. They demonstrate the ability of this method to make an important gross analysis of the modern scenarios for binary evolution, as well as to give interesting qualitative and quantitative predictions which can be checked observationally. ... The future development of the method can be considered from two different points of view. ...

Two major reasons: the number of stars isn't really seven (it's many more), and they all have different brightnesses, so that you see more or fewer of them depending on viewing conditions. The brightness of stars is measured on the magnitude scale, where the most prominent stars in the sky are around 1st magnitude, and the faintest you can see with your eye are about 6th. ... I think this makes it quite likely that the list will be truncated at Taygeta, giving six visible stars. ...
