| Abstract: |
The potential of the Pan-STARRS project and the prototype PS1 telescope for new advances in ground based astrometry are discussed. In addition we provide a set of improved analytic expressions for atmospheric refraction and extinction accurate to 1 mas up to zenith angles of 75 degrees using an extended set of meteorological data. The application of these expressions to wide field mosaic CCD imaging surveys at high air mass is discussed. The results suggest that the absolute and relative astrometric performace of such surveys may be significantly better than previously assumed, approaching and perhaps exceeding errors ≤ 1 mas to 21 magnitude. |
