论文摘要
恒星空间密度分析曾经是天文学研究的非常活跃的领域，涉及将恒星的数量转换为在天空中选定区域的限制幅度，这是每个立方PARSEC的恒星数量的图，这是距离的函数。已经发布了几种计算转换的方法，从手动电子表格到基于非常复杂的数学技术的计算机程序，用于反浏览积分方程。本文重新审视了这些技术，并比较了1913年至2003年之间七个技术的性能，并应用于模拟和真实数据。
Stellar space density analyses, once a very active area of astronomical research, involved transforming counts of stars to given limiting magnitudes in selected areas of the sky into graphs of the number of stars per cubic parsec as a function of distance. Several methods of computing the transformation have been published, varying from manual spreadsheets to computer programs based on very sophisticated mathematical techniques for deconvolving integral equations. This paper revisits these techniques and compares the performance of seven of them published between 1913 and 2003 as applied to both simulated and real data.
