The data are unpublished and we ask users to voluntarily agree to the following "Fair Use" guidelines. Kindly keep us informed of how you are using our data and of any publication plans. We trust that we will be given opportunity to review work using our unpublished data before submissions. Please acknowledge the data source as a citation, which we will provide should you be uncertain. If we feel that we should be offered participation as authors, we will let you know and we assume that an agreement on such matters will be reached prior to publishing the data. 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with our analysis we may ask that we have the opportunity to submit a manuscript before you submit one that uses unpublished data. These data may be updated or reprocessed from time to time, and it is your responsibility to insure that your publication contains the most recent revision of the data. We do not permit publications to use obsolete data. We periodically need to demonstrate progress to our sponsoring agencies. In addition to informing us of your plans, we kindly request that you help us by providing preprints and updates on publication status.
