J/A+A/442/85   Globular cluster candidates in Low SB Galaxies  (Sharina+, 2005)

Hubble Space Telescope imaging of globular cluster candidates in low surface brightness dwarf galaxies. Sharina M.E., Puzia T.H., Makarov D.I. <Astron. Astrophys., 442, 85-95 (2005)> =2005A&A...442...85S
ADC_Keywords: Galaxies, nearby ; Clusters, globular ; Photometry Keywords: galaxies: dwarf - galaxies: star clusters Abstract: Fifty-seven nearby low surface brightness dwarf galaxies (-10≳MV≳-16) were searched for globular cluster candidates (GCCs) using Hubble Space Telescope WFPC2 imaging in V and I. The sample consists of 18 dwarf spheroidal (dSph), 36 irregular (dIrr), and 3 "transition" type (dIrr/dSph) galaxies with angular sizes less than 3.7kpc situated at distances 2-6Mpc in the field and in the nearby groups: M 81, Centaurus A, Sculptor, Canes Venatici I cloud. Description: The galaxies were surveyed with the HST Wide Field and Planetary Camera 2 (WFPC2; snapshot programs GO-8192, GO-8601) with 600-second exposures taken in the F606W and F814W filters for each object.
