| galNH | Total Galactic absorption column density (cm−2) |
| galNHI | HI column density from HI4PI (cm−2) |
| Exposure | Spectra exposure time (s) |
| SrcCts | Source net counts in the 0.2-5 keV band measured from the spectra |
| RA | X-ray right ascension (J2000) before astrometric correction (Paper I), used in spectra extraction |
| DEC | X-ray declination (J2000) before astrometric correction (Paper I), used in spectra extraction |
| Rad | Source extraction radius (arcsec) |
| Ann1 | Inner radius of background extraction region (arcsec) |
| Ann2 | Outer radius of background extraction region (arcsec) |
| REGAREA_s | Geometry area of source extraction region (deg2) |
| Backscal_s | Source BACKSCAL (deg2) |
| Backscal_b | Background BACKSCAL (deg2) |
| Nempty | Number of empty channels in the background spectrum between channel 20 and 900 |
| Rate_band | Net count rate in the 0.2–2.3, 0.2–0.5, 0.5–1, 1–2, 2–4.5, 2.3–5, and 5–8 keV bands (with band suffixes of d2_2d3, d2_d5, d5_1, 1_2, 2_4d5, 2d3_5, and 5_8) |
| RateErr_band | Net count rate error in the corresponding energy band |
| BkgCts_band | Background counts in the 0.2–0.6,0.6–2.3,2.3–5, and 5-8 keV bands (with band suffixes of d2_d6_, d6_2d3, 2d3_5, and 5_8) |
| BkgCtsErr_band | Background counts error in the corresponding energy band |
| PSFCor_band | ARF “CORRPSF” correction values averaged in the 0.2–0.5, 0.5–1, 1–2, and 2.3–5 keV bands (with band suffixes of d2_d5, d5_1, 1_2, and 2d3_5) |
| FluxObsv_suffix_band | Observed energy flux (erg/cm2/s) in an observed-frame energy band s (0.5–2 keV) or t (2.3–5 keV). The suffix flags include “Med” (posterior median), “Lo1” (1-σ percentile lower limit), and “Up1” (1-σ percentile upper limit). |
| 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. |
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
