Hubble WFPC2 imaging of the Ring Nebula:
an archival data mining project by the Yerkes Astrophysics Academy for Young Scientists
Vivian Hoette (Yerkes Observatory), Max Mutchler (Space Telescope Science Institute)
The newly-formed Yerkes Astrophysics Academy for Young Scientists (YAAYS) is an NSF-funded collaboration of students, teachers, and scientists at Yerkes Observatory. We have identified archival Hubble Space Telescope (HST) observations of the Ring Nebula (NGC 6720 or M57) for an initial exercise in the emerging field of astronomical data mining and curation. The multi-wavelength images of this object with the W ide Field Planetary Camera 2 (W FPC2) made it one of the best-studied planetary nebula, and it's sheer beauty as the first Hubble Heritage release in 1999 made it an instant Hubble icon.

In recognition of this dataset's importance to both the study of planetary nebulae and the legacy of Hubble Space Telescope, we chose to prepare and preserve it for posterity. We have collected all available archival WFPC2 data, including some obtained subsequent to 1999, and are converting it into a fully and expertly prepared scientific dataset, using calibrations, methods, and software not available in the 1990s. Our treatment of this dataset will make it more immediately scienceready (and education-ready) than the standard archival products. Further, our prepared dataset will be ingested into the Hubble archive as a High Level Science Product (HLSP), making it queryable by future Hubble and NVOtype data searches. We present our prepared dataset in honor of Bob O'Dell, who has been a central figure in making the Hubble mission a reality, and in making many groundbreaking observations of nebulae with it -including the Ring Nebula.
