LSST: from Science Drivers to Reference Design and Anticipated Data Products
(Abridged) We describe here the most ambitious survey currently planned in
the optical, the Large Synoptic Survey Telescope (LSST). A vast array of
science will be enabled by a single wide-deep-fast sky survey, and LSST will
have unique survey capability in the faint time domain. The LSST design is
driven by four main science themes: probing dark energy and dark matter, taking
an inventory of the Solar System, exploring the transient optical sky, and
mapping the Milky Way. LSST will be a wide-field ground-based system sited at
Cerro Pach\'{o}n in northern Chile. The telescope will have an 8.4 m (6.5 m
effective) primary mirror, a 9.6 deg field of view, and a 3.2 Gigapixel
camera. The standard observing sequence will consist of pairs of 15-second
exposures in a given field, with two such visits in each pointing in a given
night. With these repeats, the LSST system is capable of imaging about 10,000
square degrees of sky in a single filter in three nights. The typical 5
point-source depth in a single visit in will be (AB). The
project is in the construction phase and will begin regular survey operations
by 2022. The survey area will be contained within 30,000 deg with
, and will be imaged multiple times in six bands, ,
covering the wavelength range 320--1050 nm. About 90\% of the observing time
will be devoted to a deep-wide-fast survey mode which will uniformly observe a
18,000 deg region about 800 times (summed over all six bands) during the
anticipated 10 years of operations, and yield a coadded map to . The
remaining 10\% of the observing time will be allocated to projects such as a
Very Deep and Fast time domain survey. The goal is to make LSST data products,
including a relational database of about 32 trillion observations of 40 billion
objects, available to the public and scientists around the world.Comment: 57 pages, 32 color figures, version with high-resolution figures

In Pursuit of Performance: Management Systems in State and Local Government
Chapter contribution, Information technology management in U. S. states, counties, and cities by Dufner, D. L., Holley, L. M., & Reed, B. J. (2007). Information technology management in U. S. states, counties, and cities in Patricia W. Ingraham\u27s In Pursuit of Performance: Management Systems in State and Local Government .
Based on five years of extensive research by the Government Performance Project, this volume offers a comprehensive analysis of how government managers and elected officials use management and management systems to improve performance. Drawing on data from across the nation, it examines the performance of state, county, and city governments between 1997 and 2002 within the framework of basic management systems: financial information, human resources, capital and infrastructure, and results evaluation.Key issues addressed:âą How governments strategically select elements of management to emphasize the role of leadershipâą How those governments that aim to improve performance differ from those that do not âą What effective management looks like
Through this careful, in-depth investigation, the contributors conclude that the most effective governments are not those with the most resources, but those that use the resources available to them most carefully and strategically. In Pursuit of Performance is an invaluable tool for government leaders and the scholars who study them.https://digitalcommons.unomaha.edu/gertontology_books/1000/thumbnail.jp
