Ionospheric biases correction for coordinates derived from GPS single point positioning
GNSS Global Positioning System singlepoint positioning
2015/9/10
Most GPS users employ low cost receivers. These receivers do not allow users to record the pseudorange that
they observe, but the computed coordinates. This work presents an original and simple metho...
Correction Methods, Approximate Biases, and Inference for Misclassified Data
Misclassified Data Approximate Biases
2014/12/8
When categorical data are misplaced into the wrong category, we say the data is affected by misclassification. This is common for data collection. It is well-known that naive estimators of category pr...
Potential Biases in the Detection of Planetary Systems with Large Transit Timing Variations
methods: data analysis – planetary systems – planets and satellites: detection –techniques: photometric
2011/9/29
The Transit Timing Variations (TTVs) technique provides a powerful tool to detect additional planets in transiting exoplanetary systems. In this paper we show how transiting planets with significant T...
Biases in the Quasar Mass-Luminosity Plane
black hole physics — galaxies evolution — galaxies nuclei — quasars general — accretion accretion discs
2010/11/11
We report that the reported sub-Eddington boundary in the quasar mass-luminosity plane (a departure from the Eddington luminosity limit for the highest quasar black hole masses at a given redshift) is...
Parameter estimation biases due to contributions from the Rees-Sciama effect to the integrated Sachs-Wolfe spectrum
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
The subject of this paper is an investigation of the nonlinear contributions to the spectrum of the integrated Sachs-Wolfe (iSW) effect. We derive the corrections to the iSW-auto spectrum and the iSW-...
Proposed cosmological surveys will make use of photometric redshifts of galaxies that are significantly fainter than any complete spectroscopic redshift surveys that exist to train the photo-z methods...

Large-scale atmospheric circulation biases and changes in global climate model simulations and their importance for climate change in Central Europe
Large-scale atmospheric circulation global climate model simulations Central Europe
2009/1/5
The quality of global sea level pressure patterns has been assessed for simulations by 23 coupled climate models. Most models showed high pattern correlations. With respect to the explained spatial va...
Ice thinning, upstream advection, and non-climatic biases for the upper 89% of the EDML ice core from a nested model of the Antarctic ice sheet
upstream advection EDML ice core Antarctic ice sheet
2008/11/7
A nested ice flow model was developed for eastern Dronning Maud Land to assist with the dating and interpretation of the EDML deep ice core. The model consists of a high-resolution higher-order ice dy...
