Abstract
Experiments are described which demonstrate that the dead-time constan t associated with a photon counting stellar photometer/polarimeter is readily determinable by the application of the Malus law. It is also p roposed that corrections for dead-time losses should be applied by an iteration technique to the exact equation rather than using the availa ble approximation formulae.
