Index error when loading spectrum

[Dave Sahman]

When I try to load one of my spectra, I get an Index Error. I downloaded a spectrum from SDSS to check it wasnt a problem with my spectra and still get the error. I attach as screenshot. I tried to upload the SDSS spectrum but github doesnt allow fits format files.

Any suggestions as to what's going wrong?

Thanks,
Dave

SDSS spectra encode the wavelength scale into the header, while SPLAT assumes the wavelength is an axis in the fits file. This is common enough that we have a (completely undocumented) hook to read in SDSS data:

sp = splat.Spectrum(file='spec-4030-55634-0218.fits',instrument='BOSS')
