Abstract:
Quantitative characterization of galaxy morphology is vital in
enabling comparison of observations to predictions from galaxy
formation theory. However, without significant overlap between the
observational footprints of deep and shallow galaxy surveys, the
extent to which structural measurements for large galaxy samples are
robust to image quality (e.g. depth and spatial resolution) cannot be
established. Deep images from the Sloan Digital Sky Survey (SDSS)
Stripe 82 co-adds provide a unique solution to this problem - offering
1.6-1.8mag improvement in depth with respect to SDSS Legacy images.
Having similar spatial resolution to Legacy, the co-adds make it
possible to examine the sensitivity of parametric morphologies to
depth alone. Using the gim2d surface-brightness decomposition
software, we provide public morphology catalogues for 16908 galaxies
in the Stripe 82 ugriz co-adds. Our methods and selection are
completely consistent with the Simard et al. (2011ApJS..196...11S 2011ApJS..196...11S,
Cat. J/ApJS/196/11) and Mendel et al. (2014ApJS..210....3M 2014ApJS..210....3M, Cat.
J/ApJS/210/3) photometric decompositions. We rigorously compare
measurements in the deep and shallow images. We find no systematics in
total magnitudes and sizes except for faint galaxies in the u band and
the brightest galaxies in each band. However, characterization of
bulge-to-total fractions is significantly improved in the deep images.
Furthermore, statistics used to determine whether single-Sersic or
two-component (e.g. bulge+disc) models are required become more
bimodal in the deep images. Lastly, we show that asymmetries are
enhanced in the deep images and that the enhancement is positively
correlated with the asymmetries measured in Legacy images.
Description:
SDSS Legacy imaging was performed with the dedicated 2.5-m wide-field
telescope at Apache Point Observatory (APO) in New Mexico (Abazajian
et al. 2009ApJS..182..543A 2009ApJS..182..543A, Cat. II/294). A total of around
45000deg2 of science quality images across five broad bands (ugriz)
were produced during operation and calibrated to the AB magnitude
system (Oke & Gunn 1983ApJ...266..713O 1983ApJ...266..713O). DR7 imaging is complimented
by a 640-fibre-fed pair of multi-object double spectrographs with
coverage from 3800 to 9200Å at a resolution of
λ/Δλ∼2000.
The SDSS Stripe 82 (Annis et al. 2014ApJ...794..120A 2014ApJ...794..120A, Cat.
J/ApJ/794/120) resides at 1.25°<δ<+1.25°,
-50°<α<+60° along the celestial equator in the Southern
Galactic Cap. Repeated imaging runs of Stripe 82 were carried out to
enable stacking of images and reach fainter magnitudes.
We select galaxies from the SDSS DR7 spectroscopic galaxy catalogue
that are previously analysed by Simard et al. (2011ApJS..196...11S 2011ApJS..196...11S,
Cat. J/ApJS/196/11) (S11) and which reside in Stripe 82. This provides
a sample of 16908 galaxies for which decompositions in the deeper
images can be directly compared with the more shallow reference
decompositions from S11. We avoid misclassified non-galaxy sources in
our galaxy sample by selecting targets determined to be galaxies from
SDSS fibre spectroscopy. Consequently, we have spectroscopic redshifts
for all galaxies in our sample.
Using images constructed from multiple exposures of 275deg2 in the
SDSS Stripe 82, which permit an additional 1.6-1.8mag of depth with
respect to single-exposure SDSS Legacy images, we have performed
free-nb and nb=4bulge+exp.disc (fn and n4) as well as
single-component Sersic ps decompositions on 16908 galaxies -
obtaining parametric morphologies in the u, g, r, i, z bands.
Twelve tables are released in total - one for each unique combination
of model and Xr-band pairing.

Global Notes:
Note (G1): The asymmetry and concentration indices are from the automatic
classification system (CAS) proposed by Abraham et al.
(1994ApJ...432...75A 1994ApJ...432...75A, 1996ApJS..107....1A 1996ApJS..107....1A, Cat. J/ApJS/107/1)
Note (G2): The Az index is calculated over the pixels belonging to the object or
the background. Each pixel is compared to its symmetrical counterpart
about the center of the object. If the flux in that pixel is
nσbkg higher than the flux in its symmetrical counterpart,
then the pixel is taken to be part of an asymmetrical component. Az
is the sum of the fluxes of all such pixels normalized by the total
object flux.
Note (G3): The Dz index takes advantage of the isophotal shape of the object as
measured by SExtractor. Dz is the sum of the fluxes of the object
pixels (as given by the segmentation image) with symmetrical
counterparts about the object center which do not belong to the
object. This sum is normalized by the total object flux. Dz is
computed outside of one half-light radius, and it is sensitive to
asymmetries such as tidal arms.
Note (G4): RT and RA indices are based on the indices used in local studies of
spiral arm patterns by Elmegreen, Elmegreen & Montenegro
(1992ApJS...79...37E 1992ApJS...79...37E). RT and RA each quantify the residual light
that is not characterized by the symmetric, analytic models used in
the decomposition. For both indices, the residual model-subtracted
image is either added to (RT) or subtracted (RA) by the same image
rotated by 180° about the galactic centre.
Note (G5): Absolute magnitudes incorporate k-corrections computed using kcorrect
version 4.2 (Blanton & Roweis 2007AJ....133..734B 2007AJ....133..734B)
Note (G6): Probability that the fn decomposition (two-component free-nb bulge
and exponential disc) is not required to properly characterize the
surface brightness distribution of a galaxy relative to the ps model
(single-component Sersic profile model)
Note (G7): Probability that the fn decomposition (two-component free-nb bulge
and exponential disc) is not required to properly characterize the
surface brightness distribution of a galaxy relative to the n4 model
(two-component nb=4 bulge and exponential disc model)
Note (G8): Probability that the n4 decomposition (two-component nb=4 bulge and
exponential disc model) is not required to properly characterize the
surface brightness distribution of a galaxy relative to the ps model
(single-component Sersic profile model)
Note (G9): The single-component ps model tables contain neither PpS nor Pn4
statistics and columns that pertained to the discs in the
two-component tables are either NULL or are filled with non-sensical
values in the ps tables: disc position angle, scale length,
inclination, and their associated uncertainties.
Bulge-to-total fractions are also meaningless in the ps tables.
