Abstract for MTS:
FORS2 imaging of low-density galactic globular cluster NGC6809 in B, R and Halpha. To sample this dense field adequately with the requested seeing conditions of < 0.6", the P.I. has been granted a waiver to use a non-binned CCD read-out mode. This mode is used in the OBs #184151, #184153 and 184154. The P.I. requests that twilight flats be obtained using this non-binned 200kHz,1x1,low read-out mode on each night that one of these OBs is observed. The P.I. has provided us with OBs for this purpose (OB #198474, #198475, #198476). OB#184155, intended to take shorter exposures of the brighter cluster members in seeing <0.9" uses the standard 200kHz,2x2,low CCD read-out mode.
