Most stuff on the web is not copyrighted and whatever is put on the web is up for grabs. You can add a copyright notice and people can ignore it. Do you have legal recourse? Yes, but few would pursue that and even then only if there are BIG $$ involved and you are willing to spend the time and money to pursue it. A much better approach is to not worry about it or just ask to be credited as the source. Note: Nowhere is there any information regarding what can or cannot be done with the data. I suggest adding a note on the SAC web page where the downloads are indicating the data can be used freely, but requesting a comment on any further publications or distributions indicating the source for the compiled data was SAC. BTW, I have converted the Double Star data to a more conventional form (tab separated data fields and imported it into a new database. I plan to do the same for the deep Sky Objects data. I have also done this for the SAO data (nearly 250,000 stars). Anyone interested in the database, just let me know. These databases are very easy to search and display print specific sets of data. What I have created (the database structure) I distribute freely.
