[March 20th, 2022 9:29 PM] erwan.pannier: Hello everyone @room ! Most of you recently arrived here are future GSOC22 contributors. Welcome 👏
I'm writing this message on behalf on the RADIS core team to help you get started.

[LEARN]
First, get an insight on Spectroscopy. Most of you probably aren't familiar with spectroscopy, that's totally fine. The only thing you need to now is we use it daily in research-labs all over the world to detemrine the composition of stars, or for in-the-lab experiments to measure the temperature of a flame or a plasma.
Problem is : infrared spectra of molecules are composed of millions of lines, and it takes extreme amount of computational power to compute them. RADIS does this very fast, and is actually the fastest code in the world !
Before digging in, you should at least compute a first spectrum :

  1. Go on Radis-app and compute a spectrum. https://radis.app/ It's our front-end, built by suzil, to compute spectra without having to install anything.
  2. Go on Radis-Lab and compute a spectrum. Now you're using research-grade databases. https://radis.github.io/radis-lab/
  3. Want to know more ? We even have a (WIP!) <https://github.com/radis/spectro101|Spectroscopy tutorial >project.

[DO]
You want to contribute ? Next step is to get started our code base :

  1. Read our Contributing Guidelines
  2. Have a look at our <https://github.com/radis/radis/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22|Good First Issue >and comment if you want to take on one of them
  3. Alternatively, look at our <https://github.com/radis/radis/issues/53|Long Term Todo List> and <https://github.com/radis/radis/issues/77|Documentation Todo List> : here are many ideas to contribute, that are very helpful and usually only requires few lines of codes. Quick-wins !

Have a nice journey here, and ask any question here or in the #radis:openastronomy.org channel.

Hello, this is regarding https://github.com/radis/radis/issues/62|#62. The issue mentions moving _test() from misc/signals.py in the test folder and running it, however I found no signals.py file over https://codecov.io/gh/radis/radis/tree/develop/radis/test/misc|here. Does this mean the necessary changes have been made?

Hi, after teasing around the radis web app, I noticed several input cases in which the dialog returned implicit or strange messages. I uploaded this as an issue in suzil/radis-app/issues here: https://github.com/suzil/radis-app/issues/537|#537
• First and second shots: "Failed to retrieve data from given parameters" observed in CF4 and ClONO2 and some other cases that I didn't capture, but I'm sure more than these 2
• Last shot: "ju", just a weird message observed in C2H4
I used default parameters and have rerun several times to check if these bugs (if I deem it correctly) prevail.

Hello @room, before pushing code to codebase make sure you add pre-commit hook in git by running pre-commit install, to test linting use pre-commit run --all-files. Use -am arguement before committing code to run linting test i.e. git commit -am "message" . If test fails then files would be changed and then you have to run the git commit -am "message" again. The existing linting issue has been resolved in https://github.com/radis/radis/pull/436|PR-436 so make sure to pull the latest develop branch code locally to have the updated linted files!

https://developers.google.com/open-source/gsoc/timeline
If you're interested or have questions, please get in touch with us here !

GSOC application requires you to :
• have contributed to the code (many quick-win ideas in the <https://radis-radiation.slack.com/archives/C01545R7LKB/p1647808167268399|summary post above>), merged or not-merged
• write a proposal. If you're interested in many projects, please get in touch with us as we'll try to maximise everyone's chances : we do not know yet how many projects (out of the 5) will be funded eventually , however we know that there will be at most one candidate per project. So better have all the projects covered to have as many contributors as possible !

My projects have involved me using the transit and radial velocity techniques to study the consistency and size of an exoplanet and measuring the redshift from galaxy spectral features by fitting gaussian curves to identified emission lines. I am excited to get to know and later contribute to Radis and get involved.

@ZechangSun

Hello everyone! I'm Zechang Sun and I am an undergraduate student from Tsinghua University.

I have some experience with the data processing of quasar spectra and also open source. I have contributed code to DeepIGM, which uses a convolutional neural network for damped Lya systems detection (for more details: https://arxiv.org/abs/2201.00827). I am also familiar with the so-called quasar continuum fitting problem and my code will be soon open-source once the paper is published, perhaps this summer. I have also developed some small open-source tools for astronomers by myself, for example, SpecViewer.

For programming ability, I am very familiar with python, C++, and git and also know a lot about how to design an efficient algorithm with knowledge from data structure and high performance computing. For statistical knowledge, I have a solid foundation in statistics and machine learning algorithms, which can help a lot in astronomy study.

I am very excited to get to know Radis and GSoC, and hope to contribute to Radis in GSoC. :)

Hello @room

RADIS 0.12.1 was released today ;
• main change : the default lineshape optimization routine is changed ; the new one being more robust. It will improve accuracy for extremelly thin lineshapes.
Also :
• Vaex becomes our default HDF5 library for all OS/platforms (faster!)
• you can now use arbitrary astropy units in spectrum rescaling functions
• 13 otoher fixes (including an ExoMol import problem) and (many !) documentation improvements.
Most importantly, it 0.12.1 was the contribution of 9 people including 5 first contributors. Welcome !

Hello @room the deadline to submit proposal for GSoC project is April 19 - 18:00 UTC. Reach out to the mentors to have any assistant for the project and proposal. You can share your draft to any mentor for review.

For GSOC candidates; from the OpenAstronomy team.

Attention to all the people who is planing to take part in this year GSoC programme. This is a message that the Python Software Foundation has sent to their GSoC list, and it also applies to us:

  1. Please include the sub-org name in the title of your proposal. The new system doesn't allow us any way to tag these, so your proposal could get missed or discarded as spam if you don't include it. (e.g., "[radis] title")
  2. You do actually need to choose a sub-org. Proposals that are not targeted at a specific sub-org will be rejected because we don't have mentors available for them.
  3. You need to include a link to at least one code contribution in your proposal. Generally this is a patch fixing a small bug for the sub-org you'd like to work with, random screenshots of your coursework are not sufficient. The fix does not have to merged, but you need to demonstrate that you at least know how to submit code to your chosen organization.
  4. You need to actually include a proposal describing the work you plan to do. A resume/CV is not sufficient. A single paragraph saying you like python is not sufficient. If your proposal is less than one page you have likely done something wrong.

small comment on point 4.
Does not need to be too lengthy as well. Being concise, clearly express the milestones is ~enough~ better
Think that reviewers will have to read a lot of proposal. If yours is easy to read and understand, you will likely please the reviewer 🙂

IMPORTANT:

All projects have been revised to 175 hrs (medium), which will be equivalent to 12 weeks. Please adjust your proposal timeline accordingly. Deadline is April 19 - 18:00 UTC. Make the submission on the official GSoC website. Avoid last minute submission as there is always chances of server issue. Good Luck!

Handling metadata on mixed gases?

Using calc_spectrum(), I can create a mixed gas with the argument 'mole_fraction={'H2O': 0.15, 'CO2': 0.10}'. Works very well.

First of all, I would like to express my deepest gratitude for granting me the privilege of being a GSOC 2022 contributor. I could not express how extraordinary this is to me, like a cherry on the top of all the efforts in the last 2 months.

Now, as other fellow GSOC contributors of RADIS, there will be a lot of things to learn in the upcoming summer, and I believe we are ready to take the very first step, under your guidance.

Once again, thank you for granting us this opportunity.
