Hi @Prtm2110 @minouHub - I've uploaded my proposal
as a PDF in the 2026/radis/ folder.

Note that there are two files, with different names in different folders. To make it easier, we would suggest you put it on one and create a soft link on the other pointing to the original. This will avoid that there may be differences between them.

Hi @dpshelio,
Thank you for the feedback!
Just to clarify - these are two separate proposals for two different projects:

1. RADIS (Large - 350h): 2026/radis/GSoC-2026-RADIS-Aditya-Pandey-FINAL.pdf
2. Spectra.jl (Medium - 175h): 2026/juliaastro/GSoC-2026-JuliaAstro-Aditya-Pandey-.pdf
   They are intentionally different files since they are proposals for different projects under OpenAstronomy.
   Should I still create separate PRs for each proposal, or is having both in this single PR acceptable?

@aditya-pandey-dev Interacted with the RADIS mentors and submitted several PR to the organization. Application approved 👍

[dpshelio]

@aditya-pandey-dev - please, move the juliaastro proposal as a separate PR. This will ease our review process.

Hi @dpshelio, I've moved the Spectra.jl proposal to a separate PR as requested: #49
PR #21 now contains only the RADIS proposal. Thank you for the feedback
