Removed the part about L2 being in Earth's umbra. Although this is true, the JWST is not actually at L2; it revolves around L2, specifically to avoid being in the Earth's umbra (and the moon's) and therefore avoid changes in temperature. DKMell (talk) 17:52, 13 July 2022 (UTC)
Does anyone know whether they use SAOImageDS9 or Astropy to make full color images? Both are listed under post-pipeline tools. General instructions are in this paper but it's not a software tutorial, and it doesn't mention un-redshifting very distant objects like in Dr. Becky's video (and which they didn't do completely for the deep field because the lensed galaxies were actually red.) 172.70.206.213 05:35, 14 July 2022 (UTC)
- Can we use the published image data files to produce a SMACS 0723 image with only the far-redshifted, lensed objects? 172.70.211.36 16:01, 14 July 2022 (UTC)
- There is a tutorial at https://www.galactic-hunter.com/post/jwst-data by a guy who uses PixInsight, which unlike DS9 and Astropy is commercial (€230) but a anyone can use it free for 45 days. I think the instructions for what you want to do are at https://pixinsight.com/tutorials/PCC/index.html and the data is here for SMACS 0723.
- You can use Imviz to colorize too. 172.70.207.8 00:44, 16 July 2022 (UTC)
When discussing biosignatures of exoplanets, should we draw the distinction between ozone and water? 162.158.106.113 11:58, 14 July 2022 (UTC)
