Confidence intervals for experiments with background and small numbers of events

Methods to find a confidence interval for Poisson distributed variables are illuminated, especially for the case of poor statistics. The application of `central´ and `highest probability density´ confidence intervals is compared for the case of low count-rates. A method to determine realistic estimates of the confidence intervals for Poisson distributed variables affected with background, and their ratios, is given.
