Janet Jacobsen provided the project a production database that they could use for the data challenge, and did so in a short time.

“We re-created a snapshot of the Palomar Transient Factory (PTF) database that we have operating at NERSC. This database contains the results of processing images from the PTF sky survey, as well as the results of analyzing the images for transient objects,” Jacobsen said. "One of the keys to being able to identify transient objects for follow-up telescope time is to search rapidly through the 100 million 'candidate' transient objects in the database. For supernovae, it is particularly important to detect the supernova before it reaches its peak brightness. This is why being able to test the speed of the query execution on the Dash compute system was of interest to us and the PTF collaboration."
