  R-band surface photometry is presented for 171 late-type dwarf and irregular
galaxies. For a subsample of 46 galaxies B-band photometry is presented as
well. We present surface brightness profiles as well as isophotal and
photometric parameters including magnitudes, diameters and central surface
brightnesses. Absolute photometry is accurate to 0.1 mag or better for 77% of
the sample. For over 85% of the galaxies the radial surface brightness profiles
are consistent with published data within the measured photometric uncertainty.
For most of the galaxies in the sample HI data have been obtained with the
Westerbork Synthesis Radio Telescope. The galaxies in our sample are part of
the WHISP project (Westerbork HI Survey of Spiral and Irregular Galaxies),
which aims at mapping about 500 nearby spiral and irregular galaxies in HI. The
availability of HI data makes this data set useful for a wide range of studies
of the structure, dark matter content and kinematics of late-type dwarf
galaxies.
