Citing this table

This table has an associated publication. If you use data from it, it may be appropriate to reference 2022A&A...667A..38A (ADS BibTeX entry for the publication) either in addition to or instead of the service reference.

To cite the table as such, we suggest the following BibTeX entry:

@MISC{vo:apertif_dr1_source_catalog,
  year=2020,
  title={Apertif DR-1},
  author={Apertif Team},
  url={https://vo.astron.nl/tableinfo/apertif_dr1.source_catalog},
  howpublished={{VO} resource provided by the The VO @ {ASTRON}}
}

Fields

Sorted by DB column index. [Sort alphabetically]

NameTable Head DescriptionUnitUCD
Name Source name N/A N/A meta.id;meta.main
RA RA the right ascension of the source (for the equinox of the image) deg pos.eq.ra;meta.main
E_RA RA error the error on the right ascension of the source deg pos.eq.ra;stat.error
DEC DEC the declination of the source (for the equinox of the image) deg pos.eq.dec;meta.main
E_DEC DEC error the 1-sigma error on the declination of the source deg pos.eq.dec;stat.error
Total_flux Total flux the total, integrated Stokes I flux density of the source at the reference frequency mJy N/A
E_Total_flux Total flux error the 1-sigma error on the total flux density of the source mJy N/A
Peak_flux Peak flux the peak Stokes I flux density per beam of the source mJy/beam N/A
E_Peak_flux Peak flu error the 1-sigma error on the peak flux density per beam of the source mJy/beam N/A
DC_Maj Deconvolved major axis the FWHM of the deconvolved major axis of the source deg N/A
E_DC_Maj Deconvolved major axis error the 1-sigma error on the FWHM of the deconvolved major axis of the source deg N/A
DC_Min Deconvolved minor axis The FWHM of the deconvolved minor axis of the source deg N/A
E_DC_Min Deconvolved minor axis error The 1-sigma error on the FWHM of the deconvolved minor axis of the source deg N/A
DC_PA Deconvolved PA the position angle of the deconvolved major axis of the source measured east of north deg N/A
E_DC_PA Deconvolved PA error the 1-sigma error on the position angle of the deconvolved major axis of the source deg N/A
Isl_rms Island background RMS the average background rms value of the island mJy/beam N/A
S_Code Code A code that defines the source structure 'S' for single Gaussian, 'M' for multiple Gaussian, 'C' = a single-Gaussian source in an island with other sources N/A meta.code
