Hi Yuval,
Wow! thank you for creating this; the results look very beautiful. I feel the need to apologize for the embarrassing state of the code; I have been meaning to rework it for a while now.
I would love to use your help making the bot post color photos. I was looking into it earlier, but I ran into three issues (ordered in descending priority):
As a student, I don't have much free time. I would be happy to receive your help with any of these issues.
whoops, clicked the wrong button there
Okay, great. Before going over the items you listed- I have been playing a lot with this in the last week or two so here are some impressions. Personally, I like MIRI to be very red as you can see in this collage, so I average all MIRI images to assign for the red layer. I also apply sqrt on the level-adjusted image (MIRI only) to bring forth the low luminosity dust..
So RE the points: okay, so let's go by your priority order. tackling one thing at a time, but here are my thoughts for all three.
1.a Different, or bad coordinates solutions is terrible, and I think we can ignore it. The most we could do is detect the problem and not tweet, or await manual approval. I wrote code to correct this, but then you have 30% of an image well aligned while the rest is shifted (Tarantula - big shift).
1.b about the non-linear noise, one option is to make it less visible (raise the data by power x or subtract a constant). If we prefer to clean it we can try a few things. one We can remove local median computed with a ring filter from low luminosity areas. I can start improvising or follow your lead, but first please give me some examples because there are all sorts of issues.
Hi, thanks for this most useful tool. I am playing with your method for color balance, in the aim of making color images automatically. I am now using rrr gggg bbb approach, dividing the images to three groups from MIRI no NIRCam, then average each layer. I have to overcome some speed issues but if you wish I'd like to help making color twitter-bot images. here is an example code where I use your level_adjust function![image](https://user-images.githubusercontent.com/445416/219297910-8aee1206-adcf-40ba-af70-7853ec1322e7.png)
