FILE: newmass.dat_dr2 ------ table of derived parameters from 
Kauffmann et al 2003, MNRAS, 341, 33
"Stellar Masses and Star Formation Histories for 10^5 galaxies from the SDSS"
for subset of DR2 galaxies with 14.5 < r < 17.7 and reasonable errors
in the spectral indices D_n(4000) and Hdelta_A.

If you want to use the stellar masses, please use the quantity rml50 in 
these files. If you want to use any of the other parameters, I would advise
you to read the above methods paper carefully and if in doubt,
email gamk@mpa-garching.mpg.de.

idpl, mjd, ifib:  plate ID, MJD, fiber ID

rz: k-corrected z-band absolute magnitude (k-corrections to z=0.1 from Blanton,
  assuming standard cosmology)

zz: redshift

d4n: D_n4000 (corrected for neIII contamination)

hda: Hdelta_A, emission corrected

best: min chisq MASS without dust correction

rml50: dust-corrected MASS (median of probability distribution)

rml025: dust-corrected mass (lower 2.5 percentile of probability distribution)

rml16: as above, 16th percentile of prob distr.

rml84, rml975: 84 and 97.5 percentile points of probability distr.

rmz50, rmz025,rmz975: estimates of log(M/L) in z-band (dust-corrected)

d50,d16,d84: estimates of extinction in z-band (magnitudes) 

f50,f025,f95: F_{burst}, the fraction of the stellar mass formed in a burst in
                  the past 2 Gyr. (2.5, 50 amd 95 percentile points)
