The data on this website are freely available and we encourage others to use it. Please keep us informed of how you are using our data and of any publication plans. Please reference the appropriate paper as the source of the data. Kindly inform us of publication plans well in advance of submission of a paper, so that we are given an opportunity to read and contribute to the manuscript, and be offered co-authorship if appropriate. If your work directly competes with our analysis, we may ask that we have the opportunity to submit a manuscript before you submit one that uses unpublished data.
