Column | Description |
pgc | Principal Galaxies Catalog # from LEDA |
cat | Internal catalog number used by Courteau et al. |
objname | Name used by Courteau et al. |
RA | Right Ascension in degrees (B1950) |
DEC | Declination in degrees (B1950) |
Dist | Distance in Mpc assuming D=Vcmb/H0 with Vcmb = velocity in CMB frame and H0=70 km/s/Mpc |
MI | Absolute I magnitude at assumed distance corrected for Galactic absorption following Schlegel et al. 1998 and internal absorption following Tully et al. 1998 |
logL | Total I-band luminosity assuming MsunI=4.19 |
e_L | Error in logL including errors in magnitude, dust corrections, and distance |
logW | Log of optical rotation velocity measured from resolved rotation curves typically at 2.15 disk scale lengths |
e_W | Error in logW including errors in measured velocity and inclination |
logRd | Log of I-band disk scale length in kpc at assumed distance; either mark-the-disk or B/D decomposition |
e_R | Error in logRd assuming 15% fitting error, and uncertainties in inclination and distance |
SB0 | Central I-band exponential disk surface brightness corrected for geometric deprojection to face-on with SB0=SB-Clog(b/a) and C=0.5, where C=2.5 is the transparent case |
e_SB | Error in SB0 computed by propagating errors in logRd |
VmI | Global color corrected for Galactic and internal absorption. I-band CCD but V-band either CCD or from RC3 |
e_VI | Error in color |
logab | Log of axial ratio (a/b) in I band |
ty | Morphological type code; 1st unit: RC3 code 0-10, 2nd unit: 0 nonbarred, 1 barred, 2 peculiar |
CI | Concentration index = r75/r25 in the I-band where r75 and r25 are the major axis radii that enclose 75% and 25% of the total (extrapolated) light |
