Abstract:
We present an extensive compendium of photometrically determined
structural properties for all Calar Alto Legacy Integral Field
spectroscopy Area (CALIFA)galaxies in the third data release (DR3). We
exploit Sloan Digital Sky Survey (SDSS) images in order to extract
one-dimensional (1D) gri surface brightness profiles for all CALIFA
DR3 galaxies. We also derive a variety of non-parametric quantities
and parametric models fitted to 1D i-band profiles. The galaxy images
are decomposed using the 2D bulge-disc decomposition programs IMFIT
and GALFIT. The relative performance and merit of our 1D and 2D
modelling approaches are assessed. Where possible, we compare and
augment our photometry with existing measurements from the literature.
Close agreement is generally found with the studies of Walcher et al.
(2014A&A...569A...1W 2014A&A...569A...1W) and Mendez-Abreu et al. (2017A&A...598A..32M 2017A&A...598A..32M,
Cat. J/A+A/598/A32), though some significant differences exist.
Various structural metrics are also highlighted on account of their
tight dispersion against an independent variable, such as the circular
velocity.
Description:
We have presented a diverse and homogeneous photometric catalogue of
667 CALIFA galaxies, covering the entirety of the third and final data
release. A variety of non-parametric structural parameters were
extracted from azimuthally averaged surface brightness profiles. Where
overlap between Walcher et al. (2014A&A...569A...1W 2014A&A...569A...1W) and Mendez-Abreu
et al. (2017A&A...598A..32M 2017A&A...598A..32M, Cat. J/A+A/598/A32) exists, a generally
good agreement is found, especially with the former. Our photometric
and modelling catalogue is more extensive than any existing resource
for CALIFA DR3 galaxies, especially when combined with our gri surface
brightness profiles. Our catalogue is made available to the community
in order to provide a reliable, comprehensive, and transparent
photometric reference to complement and support any exploitation of
the spectroscopic CALIFA data base.

Note on modelcor.dat: Corrected for Galactic extinction, distance, and internal
extinction (LTGs only), K correction neglected.
All errors are estimated using sky variation, except G and M20, whose errors
are estimated based on the uncertainty in defining a galaxy's edge.
Systematic errors are not included here.

Global notes:
Note (G1): Gini coefficient, a symmetry-independent concentration measurement
for the equality of light distribution amongst galaxy pixels in the i-band
image (Abraham et al., 2003ApJ...588..218A 2003ApJ...588..218A, Cat. J/ApJ/588/218; Lotz et al.,
2004AJ....128..163L 2004AJ....128..163L, Cat. J/AJ/128/163; Lisker 2008ApJS..179..319L 2008ApJS..179..319L)
Note (G2): M20, symmetry-independent concentration measurement for the
second-order moment of light of the brightest galaxy pixels that together
contribute 20 per cent of the galaxy's total light (Lotz et al.,
2004AJ....128..163L 2004AJ....128..163L, Cat. J/AJ/128/163).
Note (G3): 1D (regression in Python) and 2D (IMFIT, GALFIT) models.
Model code as follows:
0 = exponential
1 = Sersic
2 = exp+exp
3 = ser+exp
Note (G4): Quality flag as follows:
0 = Model failed to converge normally. Do not use these models.
1 = Model has converged but either fits very little of the galaxy, has one
of two components at vanishingly low surface brightness (degenerate
with a single-component model), or has abused/misused/swapped model
components relative to the intended bulge-disc paradigm.
These models may be usable with caution.
2 = Model describes only inner regions of galaxy well, describes most or all
of the galaxy but poorly, or involves slight misuse/abuse of model
components relative to the intended bulge-disc paradigm.
3 = Model is well-behaved and fairly descriptive of galaxy over most or all
of its visual extent.
Note (G5): CALIFA classification (Walcher et al., 2014A&A...569A...1W 2014A&A...569A...1W)
Note (G6): HI data (Springob et al., 2005ApJS..160..149S 2005ApJS..160..149S, Cat. VIII/77)
