| 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. |
