We describe techniques that we have developed in order to follow changes in such sources, utilizing the technique of image subtraction. In this way the stable flux in a field can be subtracted

We discuss the difficulties in measuring deviations from Gaussianity in weakly nonstationary processes (such as 1/. noise or random wal

Observation of a random pattern of

Nevertheless, no extra-solar planet was convincingly detected until recently. This is so because planets are very fa

This process is examined in the broad context of scientific measurement in general, in the context of quantum mechanics, along with the contruction of models to match the behavior observed. The relationship between classical and quantum phenomena is placed in a new framework where each is seen

Previous analyses of irregularly sampled observations suggest that it is possible to obtain results from such data sets. To evaluate the statistic
