Columns of the eFEDS AGN catalog
| Column name | Description |
|---|---|
| ID_SRC | ID of the sources in the eFEDS main X-ray catalog (Paper I) |
| RA_CORR | X-ray right ascension (J2000), astrometric corrected (Paper I) |

| CTP_LS8_DEC | Declination (J2000) of the best LS8 counterpart (Paper II) |
| CTP quality | Counterpart quality (Paper II). A threshold >=2 is adopted for the AGN catalog. |
| CTP_CLASS | Classification of the optical counterpart (Paper II). For AGN it can be 2: “Likely extraGalac-tic” or 3: “Secure extraGalactic”. |
| CTP_REDSHIFT | Redshift of the optical counterpart (Paper II) |

| LxModel | Index of the selected model for X-ray luminosity measurement. 1: single-powerlaw; 3: powerlaw + blackbody; 4: powerlaw with Gamma fixed at 2.0; 5: shape-fixed-powerlaw. The measurement with model 5 is based on photon counts and the others are considered as spectral measurements. |
| FSModel | Index of the selected model for the 0.5–2 keV flux measurement. Model 5 indicates counts-based measurements for faint sources. Model 3, 6, or 0 indicate robust spectra-based measurements. |
| FHModel | Index of the selected model for the 2.3–5 keV flux measurement. Model 5 indicates counts-based measurements for faint sources. Model 7 indicates robust spectra-based measurements. |
| NHclass | Class of measurement of AGN NH (§ 4.3) based on model 1, which can be 1: uninformative, 2: unobscured, 3: mildly-measured, and 4: well-measured. |
| galNH | Total Galactic absorption column density (cm−2) |
| galNHI | HI column density from HI4PI (cm−2) |
| SrcCts | Source net counts in the 0.2-5 keV band measured from the spectra |
| FluxObsv_suffix_band | Observed energy flux (erg/cm2/s) in an observed-frame energy band s or t. |
| FluxCorr_suffix_band | Absorption corrected energy flux (erg/cm2/s) in an observed-frame energy band s or t. |
| LumiIntr_suffix_band | Intrinsic (absorption corrected) luminosity in a rest-frame energy band s (erg/s) or at rest-frame 2keV (erg/s/eV). |
| FluxIntr_suffix_band | Absorption corrected energy flux in a rest-frame energy band s (erg/cm2/s) or at rest-frame 2keV (erg/cm2/s/eV). |
| lognH_suffix_m1 | log AGN absorption column density (cm−2) in model 1 (single-powerlaw). |
| Gamma_suffix_m2 | Slope of the primary power-law in model 3 (powerlaw + blackbody). |
| logZ_mi | log Bayesian evidence with model i, where i is the model index 0,1,2,3,4,5. |
| L2500 | The rest-frame 2500Åluminosity in erg/s/Hz |
| L5100 | The rest-frame 5100Åluminosity in erg/s/Hz |
| W1 | LS8-WISE W1 AB magnitude (Paper II) |
| W1_ERR | LS8-WISE W1 magnitude error (Paper II) |
| W2 | LS8-WISE W2 AB magnitude (Paper II) |
| W2_ERR | LS8-WISE W2 magnitude error (Paper II) |
Notes. The suffix flags in the flux-related columns (“FluxObsv”, “FluxCorr”, “FluxIntr”, and “LumiIntr”) include “Med” (posterior median), “Lo1” (1-σ percentile lower limit), and “Up1” (1-σ percentile upper limit). For “lognH” and “Gamma”, the suffix flags include “Med” (posterior median), “HLo” (1-σ HDI lower limit), “HUp” (1-σ HDI upper limit), and “KL” (KL divergence). The energy bands include s for 0.5–2 keV band, t for 2.3–5 keV band, and 2keV for monochromatic luminosity or flux at 2 keV.
