... This paper presents an overview of the CENTERFIT image centering algorithm library currently under development in the IRAF system. ... The centering algorithms employed by these applications must satisfy a wide range of efficiency and accuracy requirements, and function robustly on data sets spanning a broad wavelength, resolution, and signal-to-noise regime. This paper presents an overview of CENTERFIT, a library of 1-D and 2-D centering algorithms currently under development in the IRAF system. ...

... 5 National Astronomy and Ionosphere Center, Cornell University, Ithaca, NY 14853, U.S.A. In this paper we present new radio and near-infrared observations of a bright Halpha knot located south-east of the Cepheus OB3 association, near the ionization front that divides the S155 diffuse HII region from the Cepheus B molecular cloud. ... The larger of the small--diameter components is a blister-type compact HII region, still partly bounded by high density molecular gas. ...

... Abstract: We present a search for a low-mass Standard Model Higgs boson produced in association with a z boson decaying to charged leptons at a center-of-mass energy of s\sqrt{s}=1.96~TeV with the D0 detector at the Fermilab Tevatron collider. The search is performed in a large data set of events containing two opposite-sign leptons (electron, muon) and one or two b-tagged jets. 4:00pm, 472 Willamette Hall . ...
