Descripción
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.
