See what you think! I laid out some subsections, attempted a preamble to each, and suggested which parts you might be most interested in working on. If you are agreeable, we could get to work on our first task with this subdivision of labor! \r\n\r\nAs @janewman-pitt-edu says:\r\n\r\n> For each science area, we should:\r\n> \r\n> 1) Describe the science need in a few sentences at most\r\n> \r\n> 2) Describe the needed capability (or capabilities) in enough detail that someone could determine > whether they overlap with other needs. (E.g.:  “medium-resolution (R~4000-6000) spectroscopy covering the full optical window for i<25.3 objects with multiplexing of ~1000 over ~10 arcminute diameter fields” could work, or for a different case “optical medium-resolution spectroscopy with a highly-multiplexed spectrograph with a many-degree FoV on a 4m telescope” would also give enough information to allow identification of common needs).\r\n\r\nSo we should keep this *very brief* and as high level as he says. What do you think? Here's my suggestion for dividing up the work:\r\n\r\n* [x] Time Delay and Compound Lens Cosmography: High Precision Galaxy Mass Models from High Resolution Imaging and Spectroscopy:  Phil Marshall, Adam Bolton and others\r\n\r\n* [x] Time Delay Cosmography: Additional Monitoring to Improve Time Delay Accuracy: Eric Linder, Phil Marshall and others\r\n\r\n* [x] Time Delay Cosmography: Multi-object Spectroscopy to Improve the Fidelity of our Lens Environment and Line of Sight Characterization: Curtis McCully, Adam Bolton, Phil Marshall and others\r\n\r\n* [x] Cluster Mass Function: Spectroscopic Surveying in Cluster Fields: Will Dawson and others\r\n\r\nThe idea is that the first author would go first, and then pass on to the second for light revision and discussion. Jeff's goal is for us to complete this first pass by March 28, or in other words, the end of tis week!"},"comment":{"url":"https://api.github.com/repos/wadawson/Enabling-LSST-Dark-Energy-Science/issues/comments/202592834","html_url":"https://github.com/wadawson/Enabling-LSST-Dark-Energy-Science/issues/1#issuecomment-202592834","issue_url":"https://api.github.com/repos/wadawson/Enabling-LSST-Dark-Energy-Science/issues/1","id":202592834,"user":{"login":"drphilmarshall","id":710903,"avatar_url":"https://avatars.githubusercontent.com/u/710903?v=3","gravatar_id":"","url":"https://api.github.com/users/drphilmarshall","html_url":"https://github.com/drphilmarshall","followers_url":"https://api.github.com/users/drphilmarshall/followers","following_url":"https://api.github.com/users/drphilmarshall/following{/other_user}","gists_url":"https://api.github.com/users/drphilmarshall/gists{/gist_id}","starred_url":"https://api.github.com/users/drphilmarshall/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/drphilmarshall/subscriptions","organizations_url":"https://api.github.com/users/drphilmarshall/orgs","repos_url":"https://api.github.com/users/drphilmarshall/repos","events_url":"https://api.github.com/users/drphilmarshall/events{/privacy}","received_events_url":"https://api.github.com/users/drphilmarshall/received_events","type":"User","site_admin":false},"created_at":"2016-03-28T21:46:08Z","updated_at":"2016-03-28T21:46:08Z","body":"Hi all,\r\n\r\nAfter meeting with the rest of the \"Maximizing Science in the Era of LSST\" dark energy study group today, I added some numbers from Meng et al 2015 to the follow up high resolution imaging subsection, and wrote some very brief notes on the environment/line of sight characterization subsection.\r\n\r\n* @tommasotreu Would you mind taking a look at the content of [`sl.tex`](https://github.com/wadawson/Enabling-LSST-Dark-Energy-Science/blob/master/sl.tex#L26) and giving me some feedback, please? The hyperlink in the previous sentence will take you straight to the right line. In particular, anything we can say about the time delay lens cosmography IFU requirements on future facilities would be most helpful. For background, this repo has [a nice README](https://github.com/wadawson/Enabling-LSST-Dark-Energy-Science/blob/master/README.md). Thanks! \r\n\r\n* @cmccully I went ahead and wrote some notes on what I think we will need to do well at environment/line of sight structure characterization [in the same file, further down](https://github.com/wadawson/Enabling-LSST-Dark-Energy-Science/blob/master/sl.tex#L95). What do you think needs adding, if anything, given our charge?  You might also take a look at [the \"additional monitoring\" subsection](https://github.com/wadawson/Enabling-LSST-Dark-Energy-Science/blob/master/sl.tex#L69) too, if you have time. Thanks!\r\n\r\n* @janewman-pitt-edu Is there anything else you need in terms of specifics? \r\n\r\nThanks very much, all!\r\n\r\nPhil"}}
