... IRAF supports two kinds of parameters, auto parameters and hidden parameters, which are treated differently. auto parameters are updated every time a task is run. ... Parameters for each task are contained in `parameter files' in the uparm sub-directory in `myiraf'. ... im > imhead.longheader=yes # explicitly setting <task.param>=<value> im > eparam imhead # Edit the parameter file to update one or more # parameters at the same time # see next section . ...

Tasks in GIPSY are the application programs which do useful work for the user. ... To start a task without parameters, only the name of the task needs to be supplied. taskname To specify parameters, any number of keyword-value pairs separated by blanks can be added to the taskname: taskname keyword1 = value1 keyword2 = value2 .. ... The user can set a parameter in the task context to change requests for hidden keywords into requests for defaulted keywords. ... Tasks all run in a context . ...

... 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). ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE CHANGING UNIVERSE: EVOLUTION HAPPENS! . b) Changes in Stars . One of the great discoveries of modern science is that stars (like people) live only a measurable life-time and then die. Although the lives of the stars are enormously longer than the span of a human life, we can learn about the life story of the stars by studying them at many different stages in their life cycle, from birth to death. ...

... Fitting the observed dependence includes calculations of the polarization cross-sections averaged over particles orientation and size distribution, their normalization and the comparison of obtained dependencies with Serkowski's curve representing observational data for a chosen star. ... Variations of the polarization factors with wavelength are shown in Fig. 16 for homogeneous spheroidal particles with PF orientation. ... The distinction between prolate and oblate spheroids is also clearly seen. ...

... Second, the observatory can control the configuration, test data analysis procedures, and provide calibration solutions with the help of instrument models. This paper presents the VLT object-oriented framework for the development of ETCs (Exposure Time Calculators) and data simulators. ... Instrument simulations are being developed for the purpose of predictive calibration, instrument configuration control, and evaluation of data analysis procedures. ...
