Abstract

Observing time on major telescopes is usually allocated to individual astronomers or groups of astronomers a few nights at a time, and at most three or four such sessions might normally be available over a year. This does not mean that the astronomers concerned can relax for the other 50 weeks, but it is a measure of the relative efforts required at a research level in obtaining the data in the first place compared with the processing then needed. Usually many multiples of the time spent observing have to be spent afterwards working on the data (photographs, CCD images, spectra, photometric measurements, astrometric measurements, etc.) in order to get it into the finally desired form.
