synspec returns all nans #52

Closed iancrossfield closed 5 years ago

iancrossfield commented 6 years ago

Following the examples for synspec yields only nans: (I have to Use an alternative linelist, since defaults aren't available online): ``atm= atlas9.Atlas9Atmosphere(teff=4750.,logg=2.5,metals=-0.25) mylinelist = '/dash/exobox/proj/atmo/linelists/apogee/turbo_molec.DR12' synspec= apogee.modelspec.turbospec.synth([26,-0.25,0.25],[22,-0.3],modelatm=atm, linelist=mylinelist, wmin=15000, wmax=15500, dw=0.2) '' But the resulting synspec contains only nans.

I don't think this is an actual example from the documentation, so I'm not sure I can help with figuring this out. Also, the '201404080919' linelist is available online (I believe the code will just download it automatically or you might have to do apogee.tools.download.linelist('201404080919'), so please test first that the actual example from the documentation works. It may be that the parameters you changed are to blame for the error.

Also note that I am far from being a Turbospectrum expert and it has been a few years since I've used this code, so my ability to help with this might be very limited.
