Second submission. Some minor changes after comments from co-I's. The Dataset still says WFPC2 as WFC3 is not available as an option in APT 18.0 Assigned ID: 171 ----- Attempting Submission 1 (Thu Feb 25 20:16:04 GMT 2010) ----- HST Phase I Proposal 171 (MW-structure-18.1.apt) successfully submitted. ----- Attempting Submission 2 (Fri Feb 26 11:19:09 GMT 2010) ----- Dwarfs belonging to the Milky Way are found as contaminants in many observations of the high-redshift universe with HST. Any high-redshift study therefore becomes a census of the Milky Way's smallest stellar members. But to study the Galaxy disk's shape, many lines-of-sight are needed. We propose to capitalize on this painstakingly assembled sample of Milky Way dwarfs, by identifying and classifying them in an ongoing WFC3 Pure Parallel program that produces deep near-infrared imaging. We expect to be complete up to 26 mag, sampling the M, L and T dwarfs along at least 31 independent lines-of-sight out of the Milky Way, possibly more. From the numbers of dwarfs, we will constain current models of the size and shape of the dwarf contribution to the Milky Way.
