Appreciate the rapid and helpful responses to my queries from the PC. ----- Attempting Submission 1 (Tue Jul 03 14:24:56 GMT 2012) ----- Confirming the theoretical link between ultra-massive white dwarfs and heavy-weight intermediate mass stars. We propose to probe the theoretically predicted evolutionary link between ultra-massive O+Ne white dwarfs and stars with M_init~5-10Msolar by using HST and WFC3 to obtain good S/N (~30) imaging to ~25 mag. of 22 sq. arcmins of the young open cluster NGC6705. These observations will allow us to address gaping deficiencies in the current understanding of the late-stage evolution of heavy-weight intermediate mass stars and significantly advance the poor present level of knowledge about their role in the chemical evolution of the Galaxy and other galaxies. These observations will provide deep imaging of the extremely rich young/intermediate age open cluster NGC6705 in the F336W and F555W bands at three discrete WFC3 field pointings. The main goal of this experiment is to identify and characterise faint white dwarf cluster members from their location in the F336W, F555W color-magnitude diagram. NGC6705 is a strongly centrally concentrated open cluster which contains numerous extremely bright sources (V<12). To maximise the number of white dwarfs we detect, which is important for achieving our science goals, we need to point as close to the cluster center as possible but at the same time keep to a minimum the area of CCD that is affected by saturated pixels and overspills. Therefore, we have placed constraints on the ORIENTation of each pointing so as to ensure that the bulk of these brightest stars do not fall within our fields of view. Additionally, we have kept the proposed integration times in the F555W band, where saturation is worst, as short (350s) as still allows for parallel buffer dumps. To sub-sample the WFC3 PSF and to aid in cosmic ray and bad pixel rejection, we employ the default WFC3-UVIS BOX and LINE-3PT dither patterns.
