Voids in the PSCz Survey and the Updated Zwicky Catalog
We describe an algorithm to detect voids in galaxy redshift surveys. The method is based on the void finder algorithm of El-Ad & Piran. We apply a series of tests to determine how accurately we are able to recover the volumes of voids using our detection method. We simulate voids of different ellipticity and find that if voids are approximately spherical, our algorithm will recover 100% of the ...
متن کاملThe UCAC3 Star Catalog: A New Catalog of Optical Reference Stars for Space Surveillance
Version three of the U.S. Naval Observatory CCD Astrograph Catalog (UCAC3) was released in August 2009. As the first version of the UCAC to cover the entire sky, UCAC3 is a suitable source of optical reference stars in the R = 8 to 16 magnitude range. Containing just over 100 million objects and providing stellar positional accuracies of about 15 to 100 milliarcseconds (mas) per coordinate, UCA...
متن کاملAn updated catalog of prostate cancer predictive tools.
Accurate estimates of risk are essential for physicians if they are to recommend a specific management to patients with prostate cancer. Accurate risk estimates also are required for clinical trial design to ensure that homogeneous, high-risk patient groups are used to investigate new cancer therapeutics. Using the MEDLINE database, a literature search was performed on prostate cancer predictiv...
متن کاملTreatment of star catalog biases in asteroid astrometric observations
In this paper, we discuss the detection of systematic biases in star positions of the USNO A1.0, A2.0, and B1.0 catalogs, as deduced from the residuals of numbered asteroid observations. We present a technique for the removal of these biases, and validate this technique by illustrating the resulting improvements in numbered asteroid residuals, and by establishing that debiased orbits predict om...
متن کاملEclipsing Binaries in the Ogle Variable Star Catalog. Iv. the Pre-contact, Equal-mass Systems
We used the database of eclipsing binaries detected by the OGLE microlensing project in the pencil-beam search volume toward Baade’s Window to define a sample of 74 detached, equal-mass, main-sequence binary stars with short orbital periods in the range 0.19 < P < 8 days. The logarithmic slope of the period distribution, logN ∝ (−0.8 ± 0.2) log P , was used to infer the angular-momentum-loss (A...
