ADC_Keywords: Galaxies, nearby ; Photometry ; Morphology Keywords: galaxies: fundamental parameters - galaxies: general - galaxies: photometry - galaxies: structure Abstract: We present surface photometry and metallicity measurements for 104 nearby dwarf galaxies imaged with the Advanced Camera for Surveys and Wide Field and Planetary Camera 2 aboard the Hubble Space Telescope. In addition, we carried out photometry for 26 galaxies of the sample and for Sextans B on images of the Sloan Digital Sky Survey. Our sample comprises dwarf spheroidal, irregular and transition type galaxies located within ∼10Mpc in the field and in nearby groups: M81, Centaurus A, Sculptor and Canes Venatici I cloud. It is found that the early-type galaxies have on average higher metallicity at a given luminosity in comparison to the late-type objects. Dwarf galaxies with MB≥-12 to -13mag deviate towards larger scalelengths from the scalelength-luminosity relation common for spiral galaxies, h∝L0.5B. Description: Our sample (see Table 1) consists of 104 dwarf galaxies observed with the Wide Field and Planetary Camera 2 (WFPC2) using the WF3-fix aperture (proposals GO 8192 and 8601) and with the Advanced Camera for Surveys (ACS) (proposals 9771 and 10235). All HST observations were carried out with the filters F606W and F814W, the response characteristics of which can be transformed to the filters V and I in the Johnson-Cousins system. The exposure times were 600s in each filter for the WFPC2 sample. The ACS images were taken with the exposure times of 900 and 1200s in the F606W and F814W filters, respectively. File Summary:
