We present Stellar Locus Regression (SLR), a method of directly adjusting the instrumental broadband optical colors of stars to bring them into accord with a universal stellar color-color locus,...
Pixelation effects in weak lensing (2008)
High, F. William, Rhodes, Jason, Massey, Richard, Ellis, Richard
Weak gravitational lensing can be used to investigate both dark matter and dark energy but requires accurate measurements of the shapes of faint, distant galaxies. Such measurements are hindered by...
Pixelation effects in weak lensing (2007)
High, F. William, Rhodes, Jason, Massey, Richard, Ellis, Richard
Weak gravitational lensing can be used to investigate both dark matter and dark energy but requires accurate measurements of the shapes of faint, distant galaxies. Such measurements are hindered by...
Stubbs, Christopher W., High, F. William, George, Matthew R., DeRose, Kimberly L., Blondin, Stephane, Tonry, John L., ...
Motivated by the recognition that variation in the optical transmission of the atmosphere is probably the main limitation to the precision of ground-based CCD measurements of celestial fluxes, we...
Pixelation Effects in Weak Lensing (2007)
High, F. William, Rhodes, Jason, Massey, Richard, Ellis, Richard
Weak gravitational lensing is a promising probe of dark matter and dark energy requiring accurate measurement of the shapes of faint, distant galaxies. Such measures are hindered by the finite...
The Shear TEsting Programme 2: Factors affecting high precision weak lensing analyses (2006)
Massey, Richard, Heymans, Catherine, Berge, Joel, Bernstein, Gary, Bridle, Sarah, Clowe, Douglas, ...
The Shear TEsting Programme (STEP) is a collaborative project to improve the accuracy and reliability of weak lensing measurement, in preparation for the next generation of wide-field surveys. We...
