Catalogue with visual morphological classification of 32,616 radio
  galaxies with optical hosts
  We present the catalogue of Radio sources associated with Optical Galaxies
and having Unresolved or Extended morphologies I (ROGUE I). It was generated by
cross-matching galaxies from the Sloan Digital Sky Survey Data Release 7 (SDSS
DR 7) as well as radio sources from the First Images of Radio Sky at Twenty
Centimetre (FIRST) and the National Radio Astronomical Observatory VLA Sky
Survey (NVSS) catalogues. We created the largest handmade catalogue of visually
classified radio objects and associated with them optical host galaxies,
containing 32,616 galaxies with a FIRST core within 3 arcsec of the optical
position. All listed objects possess the good quality SDSS DR 7 spectra with
the signal-to-noise ratio $>$10 and spectroscopic redshifts up to $z=0.6$. The
radio morphology classification was performed by a visual examination of the
FIRST and the NVSS contour maps overlaid on a DSS image, while an optical
morphology classification was based on the 120 arcsec snapshot images from SDSS
DR 7.
  The majority of radio galaxies in ROGUE I, i.e. $\sim$ 93%, are unresolved
(compact or elongated), while the rest of them exhibit extended morphologies,
such as Fanaroff-Riley (FR) type I, II, and hybrid, wide-angle tail,
narrow-angle tail, head-tail sources, and sources with intermittent or
reoriented jet activity, i.e. double-double, X-shaped, and Z-shaped. Most of FR
IIs have low radio luminosities, comparable to the luminosities of FR Is.
Moreover, due to visual check of all radio maps and optical images, we were
able to discover or reclassify a number of radio objects as giant,
double-double, X-shaped, and Z-shaped radio galaxies. The presented sample can
serve as a database for training automatic methods of identification and
classification of optical and radio galaxies.
