Analysis of Bimodality in Histograms Formed from GALLEX and GNO Solar Neutrino Data

  author={Peter Sturrock},
  journal={Solar Physics},
A histogram display of the solar neutrino capture-rate measurements made by the GALLEX experiment appears to be bimodal, but that of the follow-on GNO experiment does not. To assess the significance of these results, we introduce a “bimodality index” based on the probability-transform procedure. This confirms that the GALLEX measurements are indeed bimodal (at the 99.98% confidence level) and that the GNO measurements are not. Tracking the bimodality index as a function of time shows that the… Expand

Time – Frequency Analysis of GALLEX and GNO Solar Neutrino Data
Time – frequency analysis of data from the GALLEX and GNO solar neutrino experiments shows that some features in power-spectrum analyses of those datasets are due to aliasing (a result of the factExpand
Combined Analysis of Solar Neutrino and Solar Irradiance Data: Further Evidence for Variability of the Solar Neutrino Flux and Its Implications Concerning the Solar Core
A search for any particular feature in any single solar neutrino dataset is unlikely to establish variability of the solar neutrino flux since the count rates are very low. It helps to combineExpand
A Bayesian approach to power-spectrum significance estimation, with application to solar neutrino data
The usual procedure for estimating the significance of a peak in a power spectrum is to calculate the probability of obtaining that value or a larger value by chance, on the assumption that the timeExpand
Evidence for r-Mode Oscillations in Super-Kamiokande Solar Neutrino Data
There has for some time been evidence of variability in radiochemical solar neutrino measurements, but this evidence has seemed suspect since the Cerenkov experiments have not shown similar evidenceExpand

Abstract We consider simple variate distributions, which are the special cases of general elliptically contoured and Kotz type distributions. In particular, we analyze the distributions having jointExpand

Reexamination of Possible Bimodality of GALLEX Solar-Neutrino Data
The histogram formed from published capture-rate measurements for the GALLEX solar-neutrino experiment is bimodal, showing two distinct peaks. However, the histogram formed from publishedExpand


Histogram analysis of GALLEX, GNO and SAGE neutrino data: Further evidence for variability of the solar neutrino flux
If the solar neutrino flux were constant, as is widely assumed, the histogram of flux measurements would be unimodal. On the other hand, sinusoidal or square-wave modulation (either periodic orExpand
Comparative analysis of GALLEX and GNO solar neutrino data
Abstract Since the GALLEX and GNO datasets were derived from closely related experiments, there is a natural tendency to merge them. This is perhaps appropriate for any analysis based on theExpand
GALLEX solar neutrino observations: Results for GALLEX IV

Comparative Analysis of GALLEX-GNO Solar Neutrino Data and SOHO/MDI Helioseismology Data; Further Evidence for Rotational Modulation of the Solar Neutrino Flux
If the solar neutrino flux is variable, the variability could be caused by modulation of the neutrino flux by an inhomogeneous magnetic field in the solar interior. This modulation, which requiresExpand
