Run as a service (v1.6+)
RadVel 1.6 ships an HTTP service that wraps the entire CLI workflow behind a JSON API plus an optional browser UI. Useful for non-Python clients, long-running MCMC jobs, and reproducible deployments.
docker run --rm -p 8000:8000 -v "$PWD/.runs:/data" \
ghcr.io/california-planet-search/radvel-api:latest
open http://localhost:8000/ui
See the service guide and the UI walkthrough for details. The same image is what runs in production.
Features
With RadVel you can
- Optimize
- leverages the suite of minimizers in scipy.optimize
- Run MCMC
- leverages the emcee package for MCMC exploration of the posterior probability distribution
- Visualize
- creates quicklook summary plots and statistics
RadVel is
- Flexible
- fix/float parameters that are indexed as strings (emulates lmfit API)
- convert between different parameterizations e.g.
e omega <-> sqrtecosw sqrtesinw - incorporate RVs from multiple telescopes
- Extensible
- Object-oriented programing makes adding new likelihoods, priors, etc. easy
- Scriptable
- Code can be run through a convenient Command-line Interface (CLI)
- Fast
- Kepler's equation solved in C (slower Python solver also included)
- MCMC is multi-threaded
