Obtain spectral lines from NED query

[cosimoNigro]

Hello,

it seems that it is not possible to obtain the spectral lines from a NED query.

(I am referring to these in the NED search, for clarity)

It seems that the photometry table is available via the get_table method, but this - as the name suggests - incudes only photometric measurements.
On the other hand, one can fetch the spectra with get_spectra.
But I'd like to access directly the line information.
Any workaround?

Best, and thank you!

My bad, apologies, the lines measurement are indeed in the photometry table

tab = Ned.get_table("NGC1275", table="photometry")
mask = tab["Observed Passband"] == "[O III] 5007"
tab[mask]

<Table length=1>

Isn't this a bit (semantically) confusing?
Maybe I am wrong, but I understood "photometry" as a flux measurement in a finite band, as opposed to "spectroscopy" that measure lines through a spectrometer (I'm thinking to photometric vs spectroscopic surveys).
And indeed the tables are separated in NED.

If you deem the separation not relevant, I can close the issue.

P.S. would it be useful to add to the docs a few lines with examples of fetching fluxes or lines measurements?

Thanks again.

@cosimoNigro Thanks for pointing this out. If they are separated on the NED page, I'd say it does make sense to separate them in astroquery. A documentation or feature contribution would be welcome, though I defer to @bsipocz for thoughts on whether this is implementable.
