RA Right ascension (epoch J2000)
Dec Declination (epoch J2000)
RSun Distance from Sun (kiloparsecs)
RGC Distance from Galactic center (kpc), assuming R_0=8.0 kpc
Fe/H Metallicity [Fe/H]
wt Weight of mean metallicity; essentially the number of independent [Fe/H] measurements averaged together.
EB-V Foreground reddening
VHB V magnitude level of the horizontal branch (or RR Lyraes)
(m-M)V Apparent visual distance modulus
Vt Integrated V magnitude of the cluster
MV,t Absolute visual magnitude (cluster luminosity), M_V,t = V_t - (m-M)V

vr Heliocentric radial velocity (km/s)
vLSR Radial velocity relative to Solar neighborhood LSR
sigv Central velocity dispersion sig_v (km/s)
c King-model central concentration, c = log(r_t/r_c); a 'c' denotes a core-collapsed cluster
