Abstract:
We extend the catalogue of two-dimensional,
Point-Spread-Function-corrected de Vacouleurs, Sersic,
de Vacouleurs+Exponential, and Sersic+Exponential fits of ∼7x105
galaxies presented in Meert+ (2015, J/MNRAS/446/3943) to include the g
and i bands. Fits are analysed using the physically motivated flagging
system presented in the original text, making adjustments for the
differing signal to noise when necessary. We compare the fits in each
of the g, r, and i bands. Fixed aperture magnitudes and colours are
also provided for all galaxies.
Description:
The data used in this analysis are the same 670722 galaxies fit in
Meert+ (M15; 2015, J/MNRAS/446/3943). The M15 sample was drawn from
the spectroscopic sample of the Legacy area of the SDSS DR7
(Abazajian+ 2009, II/294). The spectroscopic sample provides a
well-established sample with well-defined and tested selection
criteria. The criteria are presented in Strauss+ (2002AJ....124.1810S 2002AJ....124.1810S).
In addition to the data provided by CasJobs, M15 also used data from
the morphology catalogue of Huertas-Company+ (2011, J/A+A/525/A157 ;
hereafter referred to as H2011). H2011 is an automated morphological
classification that used a Bayesian SVM algorithm to morphologically
classify all galaxies in the spectroscopic sample based on parameters
in the SDSS DR7.
