Lunar radiation and temperatures

Pettit, E., Nicholson, S. B.·1930·The Astrophysical Journal

Abstract

Methods of observing.-The vacuum thermocouple attached to the 100-inch telescope was used as in measuring stellar radiation. A microscope cover-glass was used to separate the reflected light from the planetary heat. A fluorite screen and water-cell were used for special purposes. Reduction of the measurements-Comparison stars, whose radiometric magnitudes we have already determined, were used to reduce the galvanometer deflections to abso- lute intensities. These are expressed in terms of the radiometric magnitude of the planetary heat in a solid angle of i sq. sec. of arc. The relation of radiometric magnitude to absolute temperature is given by the equatio

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.
