Putting this here, for reference as the payload of the JSON feed link for Perseverence raws (see source in other thread here)

For the less technically minded among us...Ryan Kinnet has put up a page that grabs a listing with links to the PNG files that you can then use any browser-plugin-batch-downloader with
https://twitter.com/rover_18/status/1364309922167488512 I tried Firefox with 'DownloadThemAll' and it worked perfectly. Meanwhile THIS GUY has python code to also grab the data https://twitter.com/kevinmgill/status/1364311336000258048 |

Speaking of raw images, are these weird colorations due to something wrong with the pipeline or the cameras themselves (I'm thinking and hoping it's the former)?
Examples attached, one is a NavCam-L from yesterday (seems to have been pulled since), the other an RDC frame. -------------------- |

Yes. That's reassuring to hear. One could sort of expect this from (well, almost) off-the shelf commercial EDL cameras, but the navcams are on a whole other level. New raw images just trickling in. Yep, looks like they started download on the full quality, Bayered RDC camera views. On a side note, I found it interesting how the color balance between RDC and DDC was so different. Yes, different detector resolutions, but same vendor. -------------------- |
