The oxygen abundance estimates here are estimated using the CL01 models as discussed in Tremonti et al (2004), you should cite this paper and possibly also Brinchmann et al (2004) if you make use of the data.
In the file below, the AVG, MEDIAN, MODE give the mean, median and mode of the PDF of the SFR or SFR/M*, for each object, while P2P5, P16, P84, P97P5 are the 2.5th, 16th, 84th and 97.5th percentiles respectively. The ENTROPY key provides the entropy of the PDF defined as the sum over P ln(P) in the PDF.
