Wave front control techniques for imaging space objects at large zenith angles

The problem of mitigating atmospheric turbulence-induced distortions from imagery measured by astronomical and space surveillance telescopes operating at high zenith angles is addressed here. Most previous research in this problem has emphasized operation at relatively small zenith angles, where turbulence effects are less severe, and effects arising from relatively weak phase distortions domin...

Solar Neutrino Zenith Angle Distribution and Uncertainty in Earth Matter Density

We estimate in this paper the errors in the zenith angle distribution for the charged current events of the solar neutrinos caused by the uncertainty of the earth electron density. In the model of PREM with a 5% uncertainty in the earth electron density we numerically calculate the corrections to the correlation between [N ]5/[N ]2 and [N ]2/[N ]3, and find the errors notable. Forthcoming resul...
