Abstract:
    We present Hubble Space Telescope/WFPC2 images of sixteen dwarf
    galaxies as part of our snapshot survey of nearby galaxy candidates.
    We derive their distances from the luminosity of the tip of the red
    giant branch stars with a typical accuracy of ~12%.

Description:
    Images of sixteen galaxies were obtained with the Wide Field and
    Planetary Camera (WFPC2) aboard the Hubble Space Telescope (HST)
    between October 22, 1999 and July 26, 2001 as part of our HST snapshot
    survey of nearby galaxy candidates (Seitzer et al., 1999, BAAS, 31,
    1380; Grebel et al. 2000, ASP Conf. Ser. 221, 147). The galaxies were
    observed with 600-second exposures taken in the F606W and F814W
    filters for each object.

    For photometric measurements we used the HSTphot stellar photometry
    package developed by Dolphin (2000PASP..112.1383D).

Note (1): Here we used new accurate velocities measured by
          Huchtmeier et al. (2003, A&A, submitted) for some galaxies;
Note (2): Position of the tip of red giant branch (TRGB) and its uncertainty as
          derived with the Sobel filter
Note (3): True distance modulus with its uncertainty, which takes into 
      account the uncertainty in the TRGB, as well as uncertainties of 
     the HST photometry zero point (~0.05mag), the aperture corrections
     (~0.05mag), and the crowding effects (~0.06mag) added quadratically;
     the uncertainties in the extinction and reddening are taken to be 10%
     of their values from Schlegel et al. (1998ApJ...500..525S); (for more
     details on the total budget of internal and external systematic errors
     for the TRGB method see Mendez et al., 2002AJ....124..213M)
