The detection of radio emission from known X-ray flaring star EXO 040830−7134.7

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

import pandas as pd
pd.read_csv(filename, comment='#')
