摘要
对于同一天区底片,因覆盖范围和极限星等不同,用PDS测量时,被测量需按不同的空间限制和测光限制构成不同的子集。本文用两个PDP-11FORTRAN程序来实现了这一目的。此外,本文还对本项研究工作作了一个总结。
When the plates covering different areas and different magnitude limits in the same fieldare measured on the PDS microdensitometer. subsets of measured stars sh0uld be f0rmedaccording to the different spatial limits and the different photometric lirnits. Two PDP- 11FORTRAN programs are described to accomplish this purpose. Finally, a summary aboutour studies on applied techniques of PDS in photographic astrometry is given.
