Abstract: We are proposing several new publication metrics that are more meaningful and less sensitive to observatory-specific characteristics than the traditional ones. They fall into three main categories: speed of publication; fraction of observing time published; and archival usage. Citation of results is a fourth category, but it lends itself less well to definite statements. Applied to the bibliography of the Chandra X-ray Observatory, the median time from observation to publication is 2.36 years; after about seven years 90% of the observing time is published; the total annual publication output of the mission is 60–70% of the cumulative observing time available, assuming a two year lag between data retrieval and publication; and after seven years approximately 60% of available exposure time is published more than twice.
