6. Abstract

The extragalactic distance scale (EDS) is defined by a comparison of Cepheid Period-
Luminosity (PL) relations for nearby galaxies and the LMC, whose uncertain distance
is thereby the SOLE anchor. Studies of masers orbiting the central black hole in
NGC4258 have provided the most accurate extragalactic distance ever (7.2+/-0.5 Mpc),
and new radio data and analysis techniques will reduce the uncertainty to < 3.5%
(0.07 mag) by 2005. Since this distance is well determined and based on geometric
arguments, NGC4258 can provide a much needed new anchor for the EDS. Ultimately, the
combination of an independent measurement of H0 and measurements of CMB fluctuations
(e.g., WMAP) can be used to directly constrain cosmological parameters including the
equation of state of dark energy. In our Cycle 12 proposal, we defined a program
spanning two cycles. The Cycle 12 portion was accepted. We have acquired WFC images
and are constructing well sampled PL relations in 3 colors (BVI). The purpose of the
Cycle 13 observations is to address systematic sources of error and is crucial for
the success of the entire program. To disentangle the effects of reddening and
metallicity, and to characterize the effects of blending, we require 50 orbits to
obtain H-band photometry (NICMOS/NIC2) and high resolution images (ACS/HRC).

  Observations Description
  ------------------------

     In cycle 12, we observed two WFC fields in the galaxy NGC4258 and detected ~
     300 Cepheid variables. In cycle 13, we will observe 50 fields (one visit/orbit
     each), 26 with NICMOS/NIC2 and 24 with the ACS/HRC. The purpose of the NICMOS
     observations is to obtain H-band magnitudes, which in combination with our
     existing BVI magnitudes will enable us to disentangle the effects of reddening
     and metallicity for each star. The HRC data will enable us to estimate the
     effects of crowding and blending on our WFC photometry. Although we are
     targeting Cepheids, we will not use the cycle 13 data to construct light
     curves; therefore, the timing of the observations is unconstrained. The HRC and
     NIC2 fields are chosen to maximize the number of known Cepheids that can be
     observed within the allotted number of orbits, irrespective of roll angle. Each
     HRC visit will be split to provide F555W and F814W exposures (2 point dither).
     Each NIC2 visit will be used for F160W exposures (4 point dither). ACS/WFC
     auto-parallels with F606W obtained during HRC F555W observations will be used
     to calibrate photometry offsets, (with respect to the WFC) for coordinated
     parallel WFPC2 images we obtained in cycle 12, where the fields overlap.

  Real Time Justification

  Calibration Justification
  -------------------------


  Additional Comments
  -------------------

     We were not able to get auto-parallel exposures set up for the orbits where
     NICMOS/NIC-2 is used. It would be nice if someone at STScI could figure out how
     to do this (assuming there is enough time to read out the ACS WFC chip between
     NICMOS sub-exposures). The exposures would have to be ~ 500 seconds or shorter
     to fit within the NICMOS dither pattern. If this is possible, we would like to
     request 2 F555W exposures and 2 F814W exposures. Thank you.
