Abstract:
We look to provide a detailed description of the SPectroscopic
IDentification of ERosita Sources (SPIDERS) survey, an SDSS-IV
programme aimed at obtaining spectroscopic classification and redshift
measurements for complete samples of sufficiently bright X-ray
sources.
We describe the SPIDERS X-ray Point Source Spectroscopic Catalogue,
considering its store of 11092 observed spectra drawn from a parent
sample of 14759 ROSAT and XMM sources over an area of 5129deg2
covered in SDSS-IV by the eBOSS survey.
This programme represents the largest systematic spectroscopic
observation of an X-ray selected sample. A total of 10970 (98.9%) of
the observed objects are classified and 10849 (97.8%) have secure
redshifts. The majority of the spectra (10070 objects) are active
galactic nuclei (AGN), 522 are cluster galaxies, and 294 are stars.
The observed AGN redshift distribution is in good agreement with
simulations based on empirical models for AGN activation and duty
cycle. Forming composite spectra of type 1 AGN as a function of the
mass and accretion rate of their black holes reveals systematic
differences in the H-beta emission line profiles. This study paves the
way for systematic spectroscopic observations of sources that are
potentially to be discovered in the upcoming eROSITA survey over a
large section of the sky.
Description:
SPIDERS (SPectroscopic IDentification of ERosita Sources) is a SDSS-IV
program aimed at obtaining spectroscopic classification and redshift
measurements for complete samples of sufficiently bright X-ray
sources. We describe the SPIDERS X-ray Point Source Spectroscopic
Catalogue, which contains 11092 observed spectra drawn from a parent
sample of 14759 ROSAT and XMM sources over an area of 5129deg2
covered in SDSS-IV by the eBOSS survey. This program represents the
largest systematic spectroscopic observation of an X-ray selected
sample. A total of 10970 (98.9%) of the observed objects are
classified, and 10849 (97.8%) have secure redshifts. The majority of
the spectra, 10070 are AGN, 522 are cluster galaxies, and 294 are
stars.
SDSS-IV/BOSS spectrographs observations between 2014 and 2019.

Note (1): Spectral classification after Visual Inspection as follows:
QSO/BLAGN = broad-line quasar
BALQSO/QSOBAL = broad absorption line quasar
NALGN = narrow line AGN
BLAZAR/BLLAC = blazar
GALAXY = galaxy
STAR = star
NONE/UNDET. = unknown
Note (2): Visual Inspection confidence class as follows:
3 = secure redshift
2 = uncertain redshift
1 = poor quality redshift
0 = poor q uality data
-1 = no redshift information
