Scientific paper
The sizes, stellar surface densities, mean precision values of position and proper motion in the well known astrometric standard fields of Pleiades, UCAC, SDSS and NGC 188 are given and listed. The selection principles of astrometric standard fields for LAMOST are suggested. The significance in studying the stellar evolution and observing the open clusters and clouds near the Gould's belt is expressed. Finally, the right ascensions and declinations, galactic longitudes and latitudes at J2000.0 of 13 astrometric standard fields for LAMOST are also listed. For open clusters located in the astrometric standard fields their distance from the Sun, reddening, metallicity and age are given if available. In addition, if it is possible for arrangement of observing time another two significant clusters are added.
