Our ProblemThere are ~10,000 archival solar systemimages observed with HSTs WFPC2.Their current science products are notoptimized for moving targets.We dont have a good catalog of whats inthese images.
Our ProjectCreate the high-quality science imagesoptimized for moving targets from everyWFPC2 solar system image.Create a catalog of every object in everyWFPC2 solar system image.
Our TeamMax Mutchler (STScI) - P.I.Dr. Susana Deusta (STScI)Dr. Alberto Conti (STScI)Alex Viana (STScI)Dr. Mike Wong (Berkeley/University ofMichigan)Dr. Pamela Gay (CosmoQuest, SIUE)+ CosmoQuest Team
Hubble’sWide Field 2 WFPC2:(WF2) both the camera and it’s Planetary Camera archival images are kinda weird (PC1) Archival mosaics are drizzled to WF pixel scale -- which means PC pixels are binned by 2X No rejection of cosmicWide Field 3 rays or detector artifacts(WF3) Wide Field 4 -- or worse, bad rejections! (WF4) Also -- what is on the WF chips? How many of the WF chips have never been inspected by anyone? *
For Every Image ...1. Run CR rejection2. Run astrodrizzle (x2)3. Create PNG (x2+)4. Get and convert metadata5. Talk to JPL Horizons via telnet6. Convert coordinates and find delta in pixels7. See if "pixels" fall on the image8. Save all the relevant information to a database2,200 lines of pure Python
Some Challenges10k+ files --> 100k+ filesHow do you know what version of your codegenerated what files?How do you know you code is working?How do you keep track of every moon in 80kdifferent images?
