Data needed for fitting stellar models

timothydmorton opened this issue · comments

When we have candidate binary pairs, the most convenient way for me to receive them would be just a set of (i,j) indices, (with i < j to avoid duplicates), where the indices refer to row numbers from the entire TGAS table. I'm preparing to receive such a list so that I can quickly turn around the StarModel fits.

I will also need a similarly sized list of apparently single stars, for me to fit as a control sample, to see if there are systematic differences in age between these two samples.

@smoh if you can send me a list of about N stars (where N is about the expected number of good binary matches) that definitely do not have wide binaries, then I can get started fitting that sample.

Never mind about the control sample of singles, right now I'm just fitting thousands of randomly chosen ones as singles; we can check after the fact that they are not in binary pairs.
