The Cepheid distance will be combined with the spatially resolved spectroscopy we will obtain through Gemini observations in 2012A to determine the dynamical mass of the active supermassive black hole. We already have a reverberation mass for NGC6814, and an accurate distance is required to allow us to obtain a meaningful dynamical mass for comparison with the in-hand reverberation mass. Additionally, an accurate distance is required for any meaningful luminosity measurements in NGC6814. The face-on orientation of the galaxy precludes a Tully-Fisher distance, which is the only other viable distance indicator for spiral galaxies at ~20-30Mpc. As one of only three galaxies where the supermassive black hole mass may currently be determined through dynamical modeling AND reverberation mapping, NGC6814 acts as a linchpin for the entire active galaxy black hole mass scale (both in the local universe and at cosmological distances). It is also an anchor for the low-luminosity end of the radius-luminosity relationship, which is widely-used for black hole mass estimates out to z~6. Futhermore, recent work has shown that quasars out to z~4 may soon be used as standard candles, in which case NGC6814 could provide a crucial foundation for observations that test the expansion and the ultimate fate of the universe. The goal of this proposal is to discover Cepheids in the AGN host galaxy NGC 6814 and measure their periods, allowing us to determine the distance to NGC 6814. The core of the program is comprised of 12 visits to image NGC 6814 with WFC3/UVIS through the F555W filter. These visits require powerlaw spacing over a period of ~60 days. ORIENT should be fixed to the same value for all 12 visits to aid in the data analysis. Given these requirements, the visits should take place in the period of August-November 2012 with ORIENT~90 (the exact ORIENT is not scientifically important, but it will determine the specific range of schedulable dates). The roll ranges report shows another possible window between April-July 2013 with ORIENT~240, but this window did not appear in the visit planner. The spacing of the visits should be as near as possible to the following cadence, listed in DAYS after the first visit: 0.0, 11.0, 17.6, 22.0, 26.1, 28.8, 30.8, 33.1, 40.4, 45.2, 52.5, and 60.0 Each of these observing windows is approximately +/- 1 day in width, and visits should be scheduled as near to the MIDDLE of each window as possible. ORIENT must be fixed to the same value for all of these visits. During 5 of the above 12 visits (the visits occurring at 0.0, 17.6, 30.8, 45.2, and 60.0 days), a second orbit will be dedicated to imaging through the F814W filter at the same position and ORIENT. For all WFC3/UVIS orbits, there will be 4 exposures per filter that will be separated by a four-point dither with small maneuvers to increase the PSF sampling and a large maneuver to bridge the detector gap. We have selected the UVIS-FIX aperture to ensure consistent pointing throughout the program and to aid in the data analysis. The remaining two orbits are reserved for WFC3/IR imaging of NGC 6814 through the F160W filter. ORIENT should again be held fixed at the same value as the other visits. We also request SAA-free orbits, but this visit has no additional timing constraints. We have selected the IR-UVIS-FIX aperture to match the position of the optical images. The STEP50 sequence was chosen to provide the shortest exposure times with the best possible dynamic range while still allowing parallel buffer dumps. Note that there is an AGN at the center of NGC6814 that may cause persistence problems. The AGN is NOT the target of this program, but rather the individual Cepheid stars in the host galaxy, so the loss of information in the center few pixels of the galaxy nucleus will not create a problem for our scientific goals. Because of the potential for persistence in the nucleus of these images, we have chosen to use only the WFC3-IR-DITHER patterns to increase the PSF sampling and assist with the removal of hot and transient pixels. The key to success for this program will be power-law scheduling of the 12 visits with the F555W filter over a period of 60 days. The long duration is required to ensure that we obtain sufficient coverage of the light curves for Cepheids with periods in the range 20 − 60 days, while the power-law sampling is required to avoid redundancy of phase coverage and aliasing in the periodograms. The fixed roll angle of the spacecraft is required to simplify the data analysis, which requires finding the same individual stars in all the images of this galaxy from all of the visits. The actual value at which the roll angle is fixed does not matter. It is only important that it remain the same for ALL visits.
