Somewhat less coherent (or less standalone) materials
- Resolution worksheets developed by Dr. Luisa Rebull. You can see evolution in how I'm explaining things with time. More recent versions are more tested (and have more things broken out into different documents).
- 2020 - still in Word, now broken into 3 pieces, and modified more (due to mostly pandemic but also the way this group wanted to work): File:Resolution2020-part1.pdf and File:Resolution2020-part2.pdf and File:Resolution2020-part3.pdf
- 2019 - I moved to Word and broke it into two pieces, one of which is more "how to view fits images" and the other is more the resolution work: File:Resolution2019-part1.pdf and File:Resolution2019-part2.pdf
- L1688 Resolution Worksheet - developed in 2018 for the L1688 team
- CephC-LABS Resolution Worksheet - developed in 2017 for the CephC-LABS team
- LLAMMa Resolution Worksheet - developed in 2016 for the LLAMMa team
- IC 417 Resolution Worksheet - developed in 2015 for the IC417 team
- HG-WELS Resolution Worksheet - developed in 2014 for the HG-WELS team
- C-CWEL Resolution Worksheet - developed in 2013 for the C-CWEL team

- Questions to think about and things to try having to do with resolution
- What is the size of a typical HST image? How does it compare to a single Spitzer image, or a 'typical' Spitzer mosaic, or a single POSS plate, or the field of view of an optical telescope you have used, all compared with the size of the full moon? How does that compare to the size of a recent comet that visited the inner Solar System? or the size of a spiral arm of the Milky Way? You will have to go find on the web things like the field of view of these telescopes and these objects.
- Can you create a 3-color mosaic using just Spitzer data where the different resolutions of the various cameras is noticeable and important?
- How does the spatial resolution of all those telescopes listed above compare? (e.g., what is the smallest object you can resolve as more than a point source?)
- Are you going to laugh out loud the next time you're watching a crime drama, and someone says, "can you enhance that?" when referring to a blurry black-and-white image from a security camera, and someone else waves a magic wand and suddenly all sorts of small details are visible? (Can I wave my magic wand over that DIRBE image above and ever get that Spitzer/IRAC image?)
