These two structures are selected from a large survey volume of 1 Gpc^3, and they are the most overdense and robustly established cluster-sized overdensities at z ~ 2. BOSS1244 has the overdensity of 11.0+/-2.0 on the 15 comoving Mpc (cMpc) scale and BOSS1542 has the overdensity of 13.0+/-2.0 on the 15cMpc scale, representing the most overdense environments at high redshift. Our dedicated LBT/LUCI and MMT/MMIRS observations have confirmed >~100 galaxies at z=2.23+/-0.02 in each field, and confirmed the H-alpha emitters (H < 24.0) in these two fields, and measured the 3-D large-scale structures. Furthermore, these two fields are covered with complete wavelength observations from U-band to K-band using ground-based imaging. In Cycle-25, we propose to use eight HST/WFC3 pointings to cover the most overdense regions in each field. We will measure the detailed rest-frame optical morphology of for 78 member galaxies in BOSS1244 and 85 member galaxies in BOSS1542. These observations will determine whether the universal morphology-density relationship observed in the low-redshift Universe is already in place in and around most overdense region at z ~ 2. Combining the new HST observations with the existing multi-wavelength imaging ranging from 0.3 - 2.3 microns, optical spectroscopy, and narrow-band imaging, we will provide a robust sample of galaxies in the most massive protocluster at z=2 which could be evolved into the most massive galaxy clusters (10^15 M_sun) in later epoch. Our project contains 16 orbits. In this project, we have 2 protocluster fields: BOSS1244 and BOSS1542. In each protocluster field, we use eight pointings to map the morphology of galaxies. In this phase-II proposal, each target represents a different pointing (as stated above, we use 16 different pointings to map BOSS1244 and BOSS1542 fields). We use 1-orbit to populate each pointing. Each pointing contains 10 - 20 galaxies that resides at z~ 2.2, and we will measure the morphology in WFC3/F160W filter for these galaxies. These galaxies are randomly distributed in the WFC3 field of view. We have a special setting: we need to set the position angle (PA) for each pointings to a specific orientation range. The PA is chosen because we would like the longer axis of the detector perfectly aligns with the North direction for most of our pointings. From the current Phase-II, we tentatively set a Orientation Range for each visit, with the minOrient of ~30 and maxOrient of ~50 deg (~ 210 -- 230 deg). Please verify that under this range, the longer axis of the detector indeed aligns with North direction. For cosmic ray rejection, we use 5 different exposures to populate each orbit. We checked the HST instrumentation handbook and we found that it suggests a 5 different exposures to populate a ~2600 sec exposure for a complete rejection of cosmic rays. Specifically, we use a standard 4-point small-scale dither pattern and plus an additional exposure to populate each orbit. We think these arrangements enables us to reject cosmic ray, and provide a half-pixel subsampling of the point-spread function (PSF) for each pointing. We use a total 16 visits to populate our 16 orbits. We use each visit to populate each orbit. For each visit (orbit), we first use NSAMP= 12, SPARS=50 for the first four exposures, and then a NSAMP=9, SPARS=50 exposure for the fifth exposure. We use IR-FIX to center each pointing, enabling to perfectly center the pointing in the detector. Our galaxies are randomly distributed in each pointings.
