Modern 'all-sky' surveys require a network of calibration stars with 1) known SEDs (to properly and unambiguously account for filter differences), and 2) that are on a common photometric zero-point scale. HST enables us to establish this essential network of faint spectrophotometric standards by eliminating the time-variable Earth's atmosphere, and by exploiting the well-understood energy distributions of hot DA white dwarfs (DAWDs). Broadband HST photometry, together with ground-based Balmer line spectra, are used to derive their atmospheric model parameters (temperature & surface gravity), set the overall flux scale for each source, and determine any applicable reddening. Stars thus calibrated can be used as flux standards in any arbitrary (but well characterized) passband. From data in prior HST cycles, we have calibrated 13 DAWDs between 16.5 and 19.5 mag (in V) to sub-percent accuracy spread over the equatorial and northern sky. We now have a well appraised set of targets spanning the southern sky, where suitably faint bona-fide DAWDs were not previously available. HST/WFC3 photometry of these new targets will fill the southern void, especially relevant for LSST. This precision all-sky photometric heritage from HST benefits essentially all existing and upcoming surveys, standardizes (spectro)photometry across observatories and facilities, and directly addresses one of the current barriers to understanding the nature of dark energy. Our goal is to have a network across the sky of DA white dwarfs (DAWDs) whose SED's are calibrated to sub-percent accuracy so that 3 of them are always available at airmass below 2 at any instant from any ground based observatory anywhere. We also require them to be within the dynamic range of large telescopes (and surveys from them), which implies that they must be be fainter than 16.5 mag, and preferably fainter than 17.5 in V. We have identified such stars in the southern hemisphere on the basis of catalog searches and appraisal of ground based spectra obtained with the Goodman spectrograph at the SOAR observatory, 15 of which are the targets for this proposal. The primary observational goal of this HST proposal is to obtain photometry of our target DAWD stars in the 6 WFC3 bands we have successfully used in past cycles: F275W, F336W , F475W, F625W, F775W, and F160W. In conjunction with their spectra (in hand) these observations will determine their model parameters and line-of-sight reddening so that the incident SEDs from them are known to sub-percent accuracy fromthe near-UV through the IR. We want S/N of several hundred, with at least 3 dithered exposures per band. Since we seek sub-percent accuracy, in order to minimize systematic effects, and drifts in WFC3 system sensitivities, we need contemporaneous observations of the 3 Bohlin DA white dwarf HST standards GD71, GD153, and G191B2B. We need to spread the observations of these stars for the total duration of execution of this proposal to track any secular changes, with each of these 3 stars observed at 3 distinct epochs (ideally at the beginning, middle, and end of the duration spanned for all targets). The observations of these HST standard stars should be at the same detector location as the "unknown" targets. Our experience in past cycles has shown that observations in all bands above are necessary to achiev our goals. The parallel observations with ACS in the F475W, F625W and F775W passbands (Sloan g, r, i), obtained at any available ORIENT will image available field stars to V ~ 21 mag with signal-to-noise better than 100. The photometry from these stars on the HST system will be at par with that of the white dwarfs observed with WFC3, and in their immediate vicinity (in the context of ground based detector areas), These stars will a) directly be calibrated on the HST system in 3 of the most commonly used passbands. Since they are expected to have colors that are much redder than the DAWDs, they will provide information on color terms for ground based systems, by being co-observed with the DAWDs. The Phase-2 orbit planing must be done so that dither for the ACS parallels and for the WFC3 primary observations are coordinated, and data buffering does not clash. For this reason, we observed the primaries with a sub-array of the detector, given that we are only interested in one object. ORIENT constraints are applied to keep any bright stars that fall on the same chip (not just on the sub-array) from bleeding onto the target because of saturation, and for avoiding diffraction spikes. These precautions are necessary since our goal is to get photometry to better than 0.5 percent accuracy. The 3 HST standards, which are bright, keep exposure times very short, leading to larger on board data volumes and rates. For these pointings, the parallel observations with ACS are not done, so as to avoid data-rate conflicts. Each of the 3 bright HST standards is to be observed three times distributed over the time span of all the visits to all targets in our program. Currently, this is indicated verbally in the comments fot the relevant visits. Theses may need updating to AFTER/BEFORE constructions for scheduling, once we know what the start and end times of this program are likely to be.
