In this paper, we examine the distribution of various physical properties as a function of rs of 1040 luminous (L≳L*) extended radio galaxies (RGs) at z<0.3 selected with well-defined criteria from the SDSS (Strauss et al. 2002AJ....124.1810S), NVSS (Condon et al. 1998, Cat. VIII/65), and FIRST (Becker et al. 1995+, Cat. VIII/71) surveys. About 2/3 of the RGs are lobe dominated (LD) and 1/3 have prominent jets. If we follow the original definition of the FR types, i.e., a division based solely on rs, FRI and FRII RGs overlap in their host galaxy properties. File Summary:

Note (1): Classification, as in table 1 (with S = the angular separation between the highest surface brightness (HSB) spots on either sides of the galaxy), as follows: a = HSB spots: opposite sides of RG; Central source: not HSB; S: distance between two HSB spots; Number: 667 = Fraction: 64.1% b = HSB spot: center; Central source: extended, ≥0.1ftot; S: size of the HSB spot; Number: 289 = fraction: 27.7% c = HSB spot: center; Central source: extended, <0.1ftot; S: Distance between secondary HSB spots; Number: 38 = Fraction: 3.6% d = HSB spot: center; Central source: compact, ≥0.3ftot; S: Distance between secondary HSB spots; Number: 9 = Fraction: 0.9% e = HSB spot: center; Central source: compact, <0.3ftot; S: Distance between secondary HSB spots; Number: 37 = Fraction: 3.6% See section 3 for further details. Note (2): Where the r band has been shifted blueward by a factor of 1.1 in wavelength. Note (3): A zero sigma value indicates that SDSS didn't measure the redshift for the object, and we used the redshift from the nearest neighbor with a spectrum. Note (4): The separation between the brightest regions on either sides of the host galaxy and the total size of the radio source (rs=S/T).
