Hi Thomas,
I have done the survey- most interesting. Do you have that database, or are you hoping to create one ? Our asteroid occultation results are uploaded to either the European database (SODIS), or if a Pro-Am collaboration, we send the raw video data to the “OccultPortal”. I maintain a spreadsheet for the BAA/UK contributions – its just a list of what has been reported and some pictures. You are welcome to explore its content here:

If you know what sort of info you are after, im sure we could help you populate the db for the purpose of the project.
