A discussion of the refraction tables of Pulkovo Observatory
评普尔科沃天文台大气折射表
In the third section , some space astrometric projects , which will probably be carried on in the next decade , such as GAIA of ESA , SIM of US JPL , DIVA of Germany , FAME of US Naval Observatory and STRUVE of Pulkovo , Russia are described .
In this paper , some analyses have been done to the mean refraction of the wellknown refraction tables of Pulkovo Observatory ( Fifth edition ) .
本文介绍了普尔科沃天文台大气折射表第五版并对表列的平均折射结果进行了一些分析。
A simulative computation has been carried out with list data in the Pulkovo refraction table to find refractivity and parameters of mapping function . It is proved that all the parameters in the corrective model can be obtained by the simulation with measured values of the refraction , and concluded that the form of mapping function is secondary , the accuracy of simulation will be improved with increase of the items of continued fraction .
