  We present a two-dimensional multi-component photometric decomposition of 404
galaxies from the CALIFA Data Release 3. They represent all possible galaxies
with no clear signs of interaction and not strongly inclined in the final
CALIFA data release. Galaxies are modelled in the g, r, and i SDSS images
including, when appropriate, a nuclear point source, bulge, bar, and an
exponential or broken disc component. We use a human-supervised approach to
determine the optimal number of structures to be included in the fit. The
dataset, including the photometric parameters of the CALIFA sample, is released
together with statistical errors and a visual analysis of the quality of each
fit. The analysis of the photometric components reveals a clear segregation of
the structural composition of galaxies with stellar mass. At high masses
(log(Mstar/Msun)>11), the galaxy population is dominated by galaxies modelled
with a single Sersic or a bulge+disc with a bulge-to-total (B/T) luminosity
ratio B/T>0.2. At intermediate masses (9.5<log(Mstar/Msun)<11), galaxies
described with bulge+disc but B/T < 0.2 are preponderant, whereas, at the low
mass end (log(Mstar/Msun)<9.5), the prevailing population is constituted by
galaxies modelled with either pure discs or nuclear point sources+discs (i.e.,
no discernible bulge). We obtain that 57% of the volume corrected sample of
disc galaxies in the CALIFA sample host a bar. This bar fraction shows a
significant drop with increasing galaxy mass in the range
9.5<log(Mstar/Msun)<11.5. The analyses of the extended multi-component radial
profile result in a volume-corrected distribution of 62%, 28%, and 10% for the
so-called Type I, Type II, and Type III disc profiles, respectively. These
fractions are in discordance with previous findings. We argue that the
different methodologies used to detect the breaks are the main cause for these
differences.
