Quasi-Stellar Object (QSO, quasar)

Can SDSS quasar data help to find quasars in LAMOST?

Data

Data should be in the data/ directory.

Sloan Digital Sky Survey Data Release 14

Scope of the SDSS DR14: https://www.sdss.org/dr14/scope/.

The optical spectra catalog data specObj-dr14.fits: https://www.sdss.org/dr14/data_access/bulk/#OpticalSpectraCatalogData and description: https://data.sdss.org/datamodel/files/SPECTRO_REDUX/specObj.html or https://www.sdss.org/dr14/spectro/catalogs/.

Sloan Digital Sky Survey Quasar Catalog: Fourteenth Data Release

DR14Q_v4_4.fits is the SDSS14Q catalog: https://www.sdss.org/dr14/algorithms/qso_catalog/.

Notes

The FITS file 5305/spec-5305-55984-0563.fits is not the lite version but the full version because there it no lite file available.

Lite version: https://data.sdss.org/datamodel/files/BOSS_SPECTRO_REDUX/RUN2D/spectra/lite/PLATE4/spec.html where downloaded using instruction on: https://www.sdss.org/dr14/data_access/bulk/#OpticalSpectraPer-ObjectLiteFiles
