Query: Reclassifying symbiotic stars with 2MASS and WISE: An atlas of spectral
  energy distribution   We present a new updated catalogue of Galactic and extragalactic symbiotic
stars (SySts). Since the last catalogue of SySts (Belczynski et al. 2000), the
number of known SySts has significantly increased. Our new catalogue contains
316 known and 82 candidates SySts. Of the confirmed Systs 252 are located in
our Galaxy and 64 in nearby galaxies. This reflects an increase of $\sim$50% in
the population of Galactic SySts and $\sim$400% in the population of
extragalactic SySts. The spectral energy distribution (SED) of 334 (known and
candidates) SySts have been constructed using the 2MASS and WISE data. These
SEDs are used to provide a robust reclassification in scheme of S- (74%), D-
(15%) and D'-types (2.5%). The SEDs of S- and D-type peak between 0.8 and
1.6$\mu$m and between 1.6 and 4$\mu$m, respectively, whereas those of D'-type
exhibit a plateau profile. Moreover, we provide the first compilation of SySts
that exhibit the OVI Raman-scattered line at 6830\AA. Our analysis shows that
55% of the Galactic SySts exhibit that line in their spectrum, whereas this
percentage is different from galaxy to galaxy.
