Required observational data

A certain minimum set of data is required to make observations reducible. These are the identity of the object measured; the identity of the bandpass in which the measurement was made; the time of the observation; and, for integration-type measurements, the duration of the integration. Table gif describes the basic table-file columns in detail.
