NGC 6809

This globular cluster has been the main target for repeated observations, with the aim of measuring the GIRAFFE Radial Velocity accuracy. It has been also used for testing the system efficiency and agreement with the ESO Exposure Time Calculator. Two fields were observed, one with most object at the center of the cluster, on with most objects on the external parts. V targets between 13 and 15.Numbering, Astrometry and photometry contained in the FITS binary table are from EIS PRE-FLAMES images, (S. Zaggia, private communication).
