This system is only the third known of its kind, and uniquely features the largest observed image multiplicity (at least 6), three known images close to the cluster core, and the highest redshift quasar (z=2.8). The cluster also lenses a galaxy at z=2.3 into a giant arc. With the proposed imaging we will precisely measure the three demagnified images of the quasar close to the center of the cluster, detect the 7th image predicted by the lens model, identify additional lensed galaxies, resolve the star formation in the giant arc and the quasar host, measure an upper limit for the mass of the black hole at the centers of the cluster galaxies, and compute a precise and accurate lens model that will form the foundation of many future studies. Total of 5 bands of imaging in 7 orbits - 3 optical filters with ACS (2 orbits each) and two WFC3IR filters in a single orbit. ACS observations programmed as 3 2-orbit visits, with each visit a single filter. A total of 6 frames taken per filter, three per orbit with a gap-crossing dither step between each frame. Target aperture position is WFC1 on the first orbit, and WFC2 in the second orbit, with a slight Y POSTARG. This gives full depth in the center of the field, but maximal field area coverage otherwise. Three frames per orbit gives decent PSF sampling and CR rejection even in regions not only hit in a single orbit. I have slightly adjusted the pattern point spacing from 3.011 arcsec (giving nominally a 61.5 pixel step) to 3.00284 arcsec (giving a nominally 61.33 pixel step and hence yielding a 1/3 pixel grid in three images, of course absent field distortion...). We have restricted the roll angles for the first visit of the ACS images to avoid a brightish (12 mag) star which would otherwise be in the image or at the edge, potentially creating diffratictive/scattered light issues or saturated charge bleeding. Visit 2 and 3 are to be executed at the same angle as visit 1. WFC3-IR images are as per program GO13003. A total of 8 images - 4 per filter with small box dithers for PSF reconstruction. Straight forward.
