The Two-Point Angular Correlation Function and BATSE Sky Exposure [PDF]
, 1997 The Two-Point Angular Correlation Function is a standard analysis tool used to study angular anisotropies. Since BATSE's sky exposure (the angular sampling of gamma-ray bursts) is anisotropic, the TPACF should at some point identify anisotropies in BATSE

Crossmatching of high-proper motion L, T, and Y brown dwarfs with large photometric surveys
Open Astronomy, 2023 L, T, and Y brown dwarf (BD) exploration is a topical issue. First, the transition boundary between planets and BDs is not fully understood yet. Second, there is a phenomenon called the L/T-transition.

Properties of Foreshocks and Aftershocks of the Non-Conservative SOC Olami-Feder-Christensen Model: Triggered or Critical Earthquakes? [PDF]
, 2003 Following Hergarten and Neugebauer [2002] who discovered aftershock and foreshock sequences in the Olami-Feder-Christensen (OFC) discrete block-spring earthquake model, we investigate to what degree the simple toppling mechanism of this model is ...

K2: A new method for the detection of galaxy clusters based on CFHTLS multicolor images
, 2009 We have developed a new method, K2, optimized for the detection of galaxy clusters in multicolor images. Based on the Red Sequence approach, K2 detects clusters using simultaneous enhancements in both colors and position.

Catalogs of Compact Groups of Galaxies from the Enhanced SDSS DR12
, 2016 We apply a friends-of-friends algorithm to an enhanced SDSS DR12 spectroscopic catalog including redshift from literature to construct a catalog of $1588~N\ge3$ compact groups of galaxies containing 5179 member galaxies and covering the redshift range $0.

Catalog design, catalog maintenance, catalog governance
Library Collections, Acquisitions, & Technical Services, 2000 The design of library catalogs and the maintenance of their contents equals catalog governance, that is, professional responsibility for the catalog. The design of library catalogs and their contents are an example of the standards that are the hallmark of modern librarianship.
