In Astrometry, the term is applied to the difference between the observed position of a reference star and the position listed in the star catalog.

在天文上，本术语指的是观测的参考星的位置与星表上的该星的位置的差值。

Astrometry with new technologies created and is dedicated to the Space Telescope astrometric space orbit around the Earth observation and research on the scientific .1989 8 8, the European Space Agency launch astrometric Satellite Iba Valley satellite, which contains a 29 cm diameter reflecting telescope, four ground stations for data reception and analysis with the aim of space-based observations compiled by 120,000 to contain space for satellite measurement of star form, the location accuracy of ± 0002, parallax measurement accuracy ± 0002, on their own a year 0002, CDCDCD preliminary estimate of the above three data are now actual for the 0004,0003 and 0005; CDCDCD190 year in April the U.S. launch of the Hubble Space Telescope, containing 24 m diameter Wang C far mirror can work 15-20 years, 17-18 so you can measure the parallax of stars, are hundreds of thousands of stars of the measurement results.

伴随天体测量新技术而产生，是专门用于天体测量的空间望远镜在围绕地球的空间轨道上进行观测研究的科学。1989年8月8日，欧洲空间局发射天体测量卫星伊巴谷号卫星，它载有口径29厘米反射望远镜，4个地面观测站进行资料接收与分析，目的是要通过空间观测编出含星12万颗的空间测量星表，位置精度为±0002，测量视差的精度为±0002，自行为每年0002，CDCDCD现在初步估计上述三个数据实际为0004、0003和0005；CDCDCD190年4月美国发射哈勃空间望远镜，载有口径24米的望C远镜，可工作15—20年，可以测量出17—18等星的视差，得到几十万颗星的测量结果。

After a cross-identification between the photometric data obtained from the BATC and SDSS, a catalog containing 1553 galaxies down to r'=20.0 mag is achieved, which includes 121 spectroscopically confirmed member galaxies.

通过BATC和SDSS星表的交叉证认，得到了一个极限星等r'=20.0mag，包含1553个星系的星表，其中有121个通过分光红移证认的成员星系。

The Additional Guide Star (with star flag 5) is come into use for improving the accuracy and speed of star identification. After the cases analysis of unsuccessful star identification, giving the guide star which always cause false star identification a given star flag(such as 6), which denote that the star is a Redundant Guide Star and can't take part in the star identification processing. Through the introduction of Redundant Guide Star, the accuracy of star identification is improving. The distribution of Additional Guide Stars spread all over the whole sky, even the star sparse area.

在选取导航星的过程中，位置精度阈值的引入，使得高精度的恒星作为导航星，为高精度的卫星姿态反演奠定了基础；辅助导航星的引入，与单一使用Tycho-2星表相比引入了大量的亮星(189颗辅助导航星遍及全天球，其中亮于3等星的恒星占34.4%)，且弥补了部分天区恒星稀疏无法满足星图识别条件的不足，这将十分有利于提高星图识别速度和识别率；冗余导航星的剔除，为进一步提高星图识别率提供了可能。

In order to got the more accurate Guide Star(with star flag 0), the stars with magnitude brighter than 6.5 of J1991.25 Hipparcos catalog were chosen, after the rigorous epoch transformation, the J2000.0 Hipparcos sub-catalog was got, with the help of the information of Tycho-2 star catalog and SAO star catalog at the same epoch, the threshold of position precision is introduced, which can meet the precision of attitude determination in arc-second level.

在相同的历元J2000.0时刻，选取J2000.0 Hipparcos星表和Tycho-2星表中位置精度阈值在1角秒内的共星作为导航星，选取除导航星外的J2000.0 Hipparcos星表和SAO星表中位置精度阈值在1角秒内的共星作为辅助导航星，通过模拟星图识别失败个例分析提取冗余导航星，使其排除在导航星之外。

When using a star catalogue that is complete down to a certain limiting magnitude (i.e., the USNO-A2.0 or the UCAC ), a small number of stars (10 to 30) is usually sufficient.

当使用的星表是那种完全限定在某极限星等之下的数据的（比如：USNO-A2.0或UCAC星表），一个比较小的匹配星数目就一般足够了。

Until quite recently, the only useable catalogue for CCD observers was the Hubble Space Telescope's Guide Star Catalogue, that contains about 18 million objects.

直到目前，对于CCD观测者唯一合适可用的星表是GSC（哈勃空间望远镜的引导星参考星表），它包含1.8亿个目标。

Plates of globular cluster M3, taken with the 40cm refractor at Sheshan station of Shanghai Astronomical Observatory, are used by this work. The difference of epoch of these plates is up to 81years. The positions and absolute proper motions of 24 stars in ACT catalogue, which links with the Hipparcos Catalogue based on the International Celestial Reference System, are used as the reference frame. Using the central overlapping principle, the absolute proper motions of 534 stars in the region of about 100'×100' around the cluster are determined. After the membership determination of the stars which based on the data of proper motions, average absolute proper motion components for the cluster of -0.3±0.3 mas/yr in R.A.

本文使用上海天文台佘山40厘米折射望远镜拍摄的14张最长时间跨度为81年的球状星团M3底片的PDS扫描结果，使用与 Hipparcos星表相联系的基于国际大球惯性参考系的ACT星表中的 24颗恒星的位置和绝对自行为参考架，用中心重叠法进行天体测量归算，得到了这个星团中心附近100'×100'天区内534颗恒星的位置和绝对自行，并利用这些自行对成员概率进行了估算，得到这个星团的赤经方向绝对自行为- 0.3±0.3mas/yr，赤纬方向绝对自行为-3.1±0.3mas／yr。
