Abstract Many fundamental problems in cosmology and astrophysics remain unsettled because the value of the expansion rate is uncertain to a factor of two. The refurbished HST is providing the opportunity to break this impasse. We propose to continue a program, which. in combination with other GTO and GO work should lead to a measurement of H_0 to 10 \ Our main goal is the observation of Cepheids in 20 fields in 18 nearby galaxies, for the purpose of calibrating the best secondary distance indicators, including the infrared Tully-Fisher relation, the Planetary Nebula Luminosity Function, the Surface Brightness Fluctuation method, the type Ia supernovae standard candle and the type II supernova Expanding Photosphere Method. Measurement of Cepheids in the Virgo and Fornax clusters is also being carried out. A necessary associated goal of our proposal is strengthening the calibration of the Cepheid PL relation itself, largely via resolved study of star clusters in the LMC and M33. Unique features of this proposal include an end-to-end approach to the extragalactic distance scale, our discovery of Cepheids in Virgo, and a careful error budget for the Key Project. ------------------------------------------------------------------------------------ 5972( 14) - 03/03/97 11:59 - [ 2] Observations Description ------------------------ Cycle 5 observations may be summarized as follows. Two color observations of an LMC cluster within a single orbit will define the main sequence distance to the LMC. Two-orbit revisits of Cycle 4 galaxies NGC 3351, M100 will strengthen the period determinations of longer period Cepheids. Twelve epoch campaigns on NGC 2090, 2541, 3198, and 4725 will determine distances for these galaxies. Mostly these are single orbit visits, but in some visits F814W observations are made for reddening determination. Thus we need 16 orbits per galaxy. A twelve epoch campaign on NGC1365 will determine the distance of the Fornax cluster. This requires two-orbit visits, which, with color coverage, takes 32 orbits. The Cycle 6 galaxies, NGC 4414, 3319, 4548, 3521, and 1425 will be visited once in Cycle 5 to give a long baseline for future period determinations. Real Time Justification ----------------------- Time-critical observations: in a coherent set of observations we need to determine accurate periods for Cepheids with a wide range of possible periods. Optimal usage of HST time therefore requires a carefully planned sequence. As an example, let us look at the case of NGC 1365. We propose to begin the sequence on 6 August 1995 +/- 1 with the first V and I exposures, followed with observations spaced at 7.4 +/- 0.5 days (V+I), 15.6 +/- 0.2 days, 17.8 +/- 0.3 days, 20.2 +/- 0.3 days, 22.9 +/- 0.3 days (V+I), 26.1 +/- 0.3 days, 29.5 +/- 0.4 days, 33.7 +/- 0.6 days, 38.2 +/- 0.75 days, 43.6 +/- 1.1 days (V+I), 50.0 +/- 1.8 days, and finally 365 +/- 2 days. The last observation is to minimize aliasing problems for the longer period Cepheids. Special orientation: because of undersampling, the position and orientation must be kept fixed for the maximum number of exposures. The length of the cycle, coupled to the roll constraints, allow for only a few days tolerance in the start of a sequence, and once initiated the observing cycle must be completed as specified in the given interval without omission. We have conducted and continue with ground- based calibration observations at Palomar, Steward, Las Campanas, and Siding Spring Observatories.
