The Analysis of Counts of the Extragalactic Nebulae in Terms of a Fluctuating Density Field.

Limber, D. Nelson·1953·The Astrophysical Journal

Abstract

In this paper a method is developed for analyzing the counts of the extragalactic nebulae in terms of a fluctuating density field for the nebuiae in space. It is shown how such an analysis can lead to a determination of the parameters characterizing the distribution of the nebulae. It is shown that the effects of galactic absorption, which may well be appreciable, can be taken quite simply into account on the recent theory of Chandrasekhar and for the fluctuations in brightness of the Milky Way. The necessary expressions for analyzing the counts are developed for four separate cases so that the effects of a dispersion in the absolute magnitudes of the nebulae and of fluctuations in galactic absorption can be either included or neglected as the situation demands.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
