The data in Table B.1 were submitted by the observatories at the request of the National Research Council. The information received was not uniform; most columns represent an estimate rather than an exact count. Some categories such as personnel were difficult for the observatories to estimate, since some people had responsibilities in more than one area, and some resources were shared. For some categories, observatories did not track the numbers. Some results are for 1 quarter, and were scaled up to 1 year. In some cases, only total numbers were given over the lifetime of the observatory. Nonetheless, despite being non-uniform, the data provide useful information on the range of people involved at different observatories and the wealth of results based on data obtained at each observatory.

NOTE: Acronyms are defined in Appendix C.
a Approximate number of full-time equivalent scientists who work at the observatory.
b Approximate number of full-time equivalent personnel who work on the observatory mountain.
c Approximate number of full-time equivalent engineers, software specialists, and instrumentalists who work at the observatory.
d Approximate annual number of peer-reviewed publications based on data acquired at the observatory.
e Approximate number of proposals accepted at each different telescope at the observatory per year.
f Approximate number of different principal investigators who observe each year.
g Approximate total number of observers at the observatory each year.
h For McDonald Observatory, the HET upgrade currently going on has an additional number of contract people working on it. HET is run by McDonald for a consortium of 5 institutions. McDonald does not track papers by users of the 2.7- and 2.1-m telescopes, so these are estimates.
