Abstract:
    We present wide-area UBRI photometry for globular clusters around the
    Leo group galaxy NGC 3379. Globular cluster candidates are selected
    from their B-band magnitudes and their (U-B)0 versus (B-I)0
    colours. A colour-colour selection region was defined from photometry
    of the Milky Way and M31 globular cluster systems. We detect 133
    globular cluster candidates, which supports previous claims of a low
    specific frequency for NGC 3379.

Description:
    Broad-band UBRI images covering the Leo galaxies NGC 3379, 3384 and
    3389 were obtained using the 2.5-m Isaac Newton Telescope (INT) on
    2000 February 6 and 8.
