The detection of radio emission from known X-ray flaring star EXO 040830−7134.7
Type de record:
This is the radio light curve of known X-ray flaring star EXO 040830−7134.7 observed by MeerKAT as part of ThunderKAT. These data are part of a publication in the Monthly Notice of the Royal Astronomical Society (Driessen et al., Accepted 2021 November 25. Received 2021 November 25; in original form 2021 August 25).
The light curve is from the full-time-integration, full-frequency-integration images of VW Hyi, as processed by the LOFAR Transients Pipeline (TraP).
The columns in the file are:
- mjd: the modified Julian Date (MJD) of the observation. The MJD is given by MJD=JD-2400000.5 where JD is the Julian Date
- f_int_Jy: the integrated flux density of the source in Jansky (Jy) determined by the LOFAR TraP
- f_int_err_Jy: the uncertainty on f_int_Jy in Jansky determined by the LOFAR TraP
- freq_eff_Hz: the effect frequency in Hertz (Hz) as determined by the LOFAR TraP
- taustart_ts: the ISO 8601 time of the observation in Coordinated Universal Time (UTC)
The files were made using the Pandas package, so we recommend Python users load them using
