Since before the invention of the telescope, astronomers have been classifying and cataloguing objects, so that there are now in excess of 200 such catalogues. Thus, knowing which catalogue is most appropriate to the task at hand is an important tool in observational astrono

Die Vitaminanreicherung der Haushaltskost,to film, but it suffers from several sources of noise. We illustrate how to reduce noise by backing and applying flat, bias, and dark frames. We show how to determine the linearity of a CCD and how to recognize and deal with artifacts such as bad pixels, cosmic rays, and saturation.

Beiträge zur Ernährungswissenschaftesults may have precision, self-consistency, and/or accuracy close to the real result. Results may have random errors and/or systemic errors to be addressed. This chapter explains the techniques for calculating and minimising the errors within an experiment as well as methods to propagate the errors
