As expected for the DASH, many of the exposures have POS TARG that take the target outside th e aperture.
The 6 pc DASH: A WFC3 1.6 micron Survey of the Orion Integral Shaped Filament
We propose a 1.6 micron WFC3 survey of the 6 pc long integral shaped filament (ISF) in the Orion A cloud using the DASH (drift and shift) method. At a distance of 388 pc, the 6000 solar mass ISF is the nearest region of massive star formation, sits directly behind the Orion Nebula, and hosts the Orion Nebula Cluster with over 2000 low mass stars. It is the best laboratory for understanding the network of processes, such as gas fragmentation and collapse, feedback from outflows and radiation, and dynamical interations, found in massive filamentary clouds. Using the DASH method, we will efficiently map a 6 x 0.9 pc strip along the length the ISF with 80 AU resolution in the F160W band. With these data we will search for multiple systems, obtaining excellent statistics on multiplicity as a function of environment, resolve protostellar envelopes and edge-on disks, and comparing to previous HST data, measure proper motions of stars and search for time variable scattered light nebulae. These observations will build on a long legacy of ISF observations, and they will set the stage for observations with JWST and WFIRST.
We will use the new technique for wide-field NIR imaging with HST described by Momcheva et al. (2016), which became available for general use in Cycle 25. With this method one can observe eight adjacent pointings (each covering the 2' x 2' field of view of the WFC3/IR camera) in a single orbit. We will map an area of about 4' x 8' (or 2 by 4 pointings) per orbit, and will use 14 orbits in order to cover the ISF. These will be done in the F160W filter. The SPARS25 sampling is used with 11 samples in the first exposure and 12 samples in the remaining exposures. The number of guide stars is set to single.
