0 Assigned ID: 89 ----- Attempting Submission 1 (Mon Apr 04 22:20:49 GMT 2016) ----- The spacings between visits are critical to ensure optimal sampling of Cepheid light curves with the desired periods (8-80d). I set a limit of +-0.5d for each visit but this can be relaxed a bit if needed (say, up to +-1d) The first 8 visits share a single roll angle that was chosen to obtain as many of the observations at a fixed orientation that can be maintained for as long as possible, near the start of the cycle. The last 4 visits share a single roll angle that was chosen to maximize FOV overlap with the first set of 8 visits *and* to maintain the desired temporal sampling. The WFC3/IR observations have POS-TARGs that maximize overlap of this detector over both roll angles *and* provide maximum coverage of star-forming regions where the Cepheids are expected to be. We understand it is unlikely that these specific roll angles will result in suitable guide stars; feel free to modify them as needed. It is likely you wil then have to switch some visits (#7, #8) to share the orientation of the last 4 instead of the first set for them to schedule. We will need to tweak the IR POS-TARGs once we settle on the final roll angles. -1385574821 ----- Attempting Submission 1 (Wed Jul 20 14:50:54 GMT 2016) ----- A Cepheid Distance to NGC 4051 We propose to measure an accurate Cepheid-based distance to the narrow-line Seyfert 1 (NLS1) galaxy NGC 4051, the nearest and one of the best-studied objects in its class. Distances quoted in recent literature range from 9 to 18 Mpc. A precision distance is necessary in order to understand the gas flow energetics to better than a factor of four, and indeed to determine whether the accretion rate is typical of other NLS1s (if at the maximum distance currently assumed) or simply typical of normal Seyfert 1 galaxies (if at the minimum distance). A precision distance is also required to effect a direct comparison of (distance-dependent) stellar and gas dynamical measurements of the central black hole mass with that measured by (distance-independent) reverberation mapping. NGC 4051 is one of fewer than 10 nearby reverberation-mapped AGNs, and the only one classified as an NLS1, for which such black hole mass comparisons currently are possible, and for which there is no other path to a precise distance.
