Data ingest request from: Zhang et al. 2018

[jgizis]

Article title: "Primeval very low-mass stars and brown dwarfs – III. The halo transitional brown dwarfs"

https://academic.oup.com/mnras/article/479/1/1383/5001885

the supplementary data on the website includes X-Shooter visible and IR spectra of L subdwarfs.

Also has a lot of modeled parameters worth ingesting.

@jgizis , would you or a student be interested in helping with this? E.g., I could put together a spreadsheet with the data we need to ingest and y'all could populate. That would help a lot.

It would also help to upload the relevant spectra files to this issue.

[kelle]

or @zjzhang42, want to help?

[jgizis]

Ok, I will confess that I submitted this because my super-naive attempt to read the fits files with specutils failed, so I can't do that part. But I am happy to populate a table with the fitted parameters from this and the other papers in the series.

(Although I was able to read the supplement file in 2019MNRAS.486.1840Z with no problem.).

[jgizis]

Oh, looking at the supplemental files I think Paper IV has supplemental files that include many of the spectra from the earlier papers.

@kelle Hey, just FYI I am not the first author - Zenghua Zhang.

[kelle]

Ah, apologies for my confusion!

[kelle]

Here's a sheet to fill out for the missing spectra: SIMPLE Spectra Ingest Template

And for the modeled parameters: SIMPLE Modeled Parameters Template

Are all the sources already in or do they need to be added as well?

[kelle]

It looks like symmetric uncertainties are provided for all of the modeled parameters. If that's not the case, let's discuss more. There's a plan to deal with asymmetric uncertainties but it's not implemented yet (#484 ).

[jgizis]

ok. I think the sources are all already in but if any are not I'll let you know.
