Excerpt from Observations of Double Stars It appears from this table that at all distances to which the observations extend the measurements of direction are more precise than those of distance and that this dif ference is especially marked in the case of very close and difficult Objects, agreeing in this respect with the experience of most other observers. This superior accuracy of the position angles in the present case is the more remarkable from the circum stance that the distances in general depend upon a greater number of settings of the micrometer than do the position angles, the normal number of pointings being from three to five settings of the position circle and either two or three double distances, i. E. Four to six pointings, for the distance between the stars. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
