Abstract
Highly binned power spectra of source intensity reveal both source variability and instrumental effects. The latter effects have to be fully understood before any serious attempt can be made to measure source variability. Analytic expressions are developed that may be used to remove instrumental effects from data collected with EXOSAT. Some problems with the estimation of parameter values from power spectra are also discussed.Keywords
