What are some freeware options for fitting radial velocity data?

AI Thread Summary
Freeware options for fitting radial velocity data include Systemic Console, available at www.oklo.org, which is supported by a collaborative community focused on finding optimal fits for various systems. Users express interest in programming their own solutions, with offers to provide guidance on creating a program that generates compatible data for visualization in Gnuplot. There is a desire for additional resources or write-ups to assist those with limited programming skills in developing such tools. The discussion highlights the need for accessible software solutions in the field of radial velocity analysis. Overall, the community is eager to share knowledge and resources for fitting Keplerian models to data.

Hi all,
I am attempting to find the best Keplerian fit to the Radial velocity data vs. Time such as this plot: http://austral.as.utexas.edu/planets/hd37605/hd37605.html
I was wondering whether anyone could suggest some freeware that might be able to help me out. Any information would be helpful.
If at all possible, suggestions for freeware that runs in windows would be awesome!

Do you have any interest in programming? If so, I could show you how to program such a beast yourself, so that it generates data that can be used to draw a similar graph in Gnuplot.
 
Sorry for bringing up the old post but...

NoobixCube:

There is a program called Systemic Console that can be obtained @ www.oklo.org. There is a whole group of people that collaborate to find the best fits for a wide range of systems. And best of all, everything is free.

shalayka:

I would be interested if you could provide some sort of basic writeup of what would be needed to write such a program. I have been somewhat interested in programing for a while (although my skills are still extremely limited) and that sounds like it would be a very interesting/educational project.
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
