# LOFAR H-ATLAS catalogue

This catalogue has been generated in the H-ATLAS field using PyBDSF. More details about data reduction and analysis can be found in Gurkan et al. 2018 (http://adsabs.harvard.edu/abs/2018MNRAS.475.3010G) and Hardcastle et al. 2016 (http://adsabs.harvard.edu/abs/2016MNRAS.462.1910H).

The following text describes the various columns in the catalogue:

1. `Source_id` - Radio source ID
2. `Isl_id` - Island ID assigned by the source extraction software PyBDSM
3. `RA` - Radio RA (J2000)
4. `E_RA` - Error on radio RA
5. `DEC` - Radio declination (J2000)
6. `E_DEC` - Error on radio declination
7. `Total_flux` - Total flux in Jy
8. `E_Total_flux`
9. `Peak_flux` - Peak flux in Jy
10. `E_Peak_flux`
11. `Maj` - Major axis of the source in degrees
12. `E_Maj`
13. `Min` - Minor axis of the source in degrees
14. `E_Min`
15. `PA` - Position angle of the source
16. `E_PA`
17. `Isl_Total_flux` - Total flux inside the island fitted by PyBDSM in Jy
18. `E_Isl_Total_flux`
19. `Isl_rms` - RMS value within the fitted island in Jy
20. `Isl_mean` - Mean flux within the island (values have been defaulted to 0)
21. `S_code` - Source morphology; S: single component, M: multiple components
