Your project to detect brown dwarf companions sounds very interesting. However, I just want to sound a note of caution about trying to detect their spectra by direct fitting with...

Ah, your plot makes the issue clearer. I think the problem is that the vacuum to air conversion we are using is not valid outside of optical wavelengths.

I am excited about all of these enhancements for dealing with varying spectral resolution, and like you showed me a few weeks ago, I think it is working very well....

I think this sounds quite reasonable for the next release, and I think #32 at least should be attainable as well.

If all you are after is intuition, and not some smooth function to be used in an optimization routine, I think this might be accomplished more easily by simply taking...

Although the covariance matrix for the emulator and the covariance both appear in the likelihood calculation, they have different origins and serve different purposes. Once the emulator is tuned to...

It is true that the current sampling routines are a bit verbose for a [default option](https://newton.cx/~peter/2012/12/silence-is-golden/). I like your idea to provide a verbose flag with the output you've demonstrated....

Hi @AngelicaJara , I'm sorry that the configuration file is not working properly for you. Could you paste the contents of your `config.yaml` here or link to them via something...

For the purposes of fitting a spectrum, continuum normalization is not necessary. The purpose of introducing the Chebyshev polynomials is to essentially fit for error in the flux calibration. Fitting...

I do think it's possible to rewrite the Habib et al. likelihood from the product of tensors. And to be honest, it would probably make the whole thing a bit...
