Can SDSS quasar data help to find quasars in LAMOST?
Data should be in the data/ directory.
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/.
DR14Q_v4_4.fits is the SDSS14Q catalog:
https://www.sdss.org/dr14/algorithms/qso_catalog/.
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

LAMOST DR5 v3: http://dr5.lamost.org/.
The general catalog dr5_v3.csv is available on:
http://dr5.lamost.org/catalogue.
LAMOST QSO catalogs are described on: http://explore.china-vo.org/data/lamost-quasar/intro.
The main file is dr4dr5_qso_massflagged_v04.fits of DR4 and DR5.
Other files are:
dr1_knownquasars_v01.fits: DR1 known quasars.dr1_newquasars_v01.fits: DR1 new quasars.dr23_table_v01.fits: DR2 and DR3 quasars.lamost_phase1_v02.fits: full catalog.
