Description
The IAC Stripe 82 Legacy Survey is a new co-addition of the SDSS Stripe
82 data (Abazajian et al. 2009), especially reduced to preserve the
faintest surface brightness features of this data set. The survey maps a
2.5 degree wide stripe along the Celestial Equator in the Southern
Galactic Cap (-50$^{\circ}$ $<$ R.A. $<$ 60$^{\circ}$,
-1.25$^{\circ}$ $<$ Dec.$<$ 1.25$^{\circ}$) with a total of 275
square degrees in all the five SDSS filters (u,g,r,i,z). The new
reduction includes an additional and deeper band (rdeep), which is a
combination of g, r and i bands. The average seeing of the Stripe82
dataset is around 1 arcsec. The mean surface brightness limits are
$\mu_{lim}$[3$\sigma$,10$\times$10 arcsec$^{2}$] = 27.9, 29.1, 28.6,
28.1 and 26.7 mag arcsec$^{-2}$ for the u, g, r, i and z bands
respectively. The significant depth of the data and the emphasis on
preserving the characteristics of the background (sky + diffuse light)
through a non-aggressive sky subtraction strategy make this dataset
suitable for the study of the low surface brightness Universe. In this
research note we present a new data release with improved sky-rectified
images. This new data-set is published on the survey webpage and is
publicly available for the community.

We are a large, diverse, and very active research group aiming to provide a comprehensive picture for the formation of galaxies in the Universe. Rooted in detailed stellar population analysis, we are constantly exploring and developing new tools and ideas to understand how galaxies came to be what we now observe.
