Radio sources associated with Optical Galaxies and having Unresolved or
  Extended morphologies (ROGUE). I. A catalog of SDSS galaxies with FIRST core
  identifications
  We present the catalog of Radio sources associated with Optical Galaxies and
having Unresolved or Extended morphologies I (ROGUE~I), consisting of 32,616
spectroscopically selected galaxies. It is the largest handmade catalog of this
kind, obtained by cross-matching galaxies from the Sloan Digital Sky Survey
(SDSS) Data Release 7 and radio sources from both the First Images of Radio Sky
at Twenty Centimetre (FIRST) survey and the NRAO VLA Sky Survey \textit{without
imposing a limit to the radio flux densities}. The catalog provides a
\textit{visual} classification of radio and optical morphologies of galaxies
presenting a FIRST core within 3\arcsec\ of the optical position. The radio
morphological classification is performed by examining the radio-optical
overlays of linear sizes equal to 1 Mpc at the source distance, while the
120\arcsec\ image snapshots from the SDSS database are used for optical
classification. The results of our search are: (i) single-component unresolved
and elongated, radio sources constitute the major group in the ROGUE I catalog
($\sim$90%), and $\sim$8% exhibiting {\it extended} morphologies, (ii) samples
of 269, 730, and 115 Fanaroff-Riley (FR) type I, II, and hybrid galaxies,
respectively, are presented (iii) we report 55 newly discovered giant/possible
giant, 16 double-double, 9 X-shaped, and 25 Z-shaped radio sources, (iv) on the
optical front, most galaxies have elliptical morphologies ($\sim$62%) while
spirals form the second major category ($\sim$17%) followed by distorted
($\sim$ 12%) and lenticular ($\sim$7%) morphologies, (v) division between the
FR I and the FR~II sources in the radio-optical luminosity plane is blurred, in
tune with recent studies.
