Light Curves of 3C 390.3

---

• X-ray light curve
  • Data: [X-ray light curve]
  • Reference: Leighly, K.M., et al. 1997, ApJ. 483, 767 [Abstract]
  • Format of Data:
    • Column (1): JD - 2400000
    • Column (2): Counts per second in 1-2 keV band.
    • Column (3): Uncertainty in flux, same units as column (2).
  • Additional Notes: From Table 1 of Leighly et al. One count per second corresponds to approximately 2.93 x 10^-11 ergs s^-1 cm^-2 for a photon index of Gamma = 1.7 and absorbing column N_H = 1.15 x 10²¹ cm² and 3.04 x 10^-11 ergs s^-1 cm^-2 for a photon index of Gamma = 1.82 and the same absorbing column.

  • Reference: O'Brien, P.T., et al. 1998, ApJ, 509, 163 [Abstract]
  • Format of Data:
    • Column (1): JD - 2400000
    • Column (2): Flux. Continuum in units of 10^-15 ergs s^-1 cm^-2 Å^-1, emission lines in units of 10^-13 ergs s^-1 cm^-2.
    • Column (3): Uncertainty in flux, same units as column (2).
  • Additional Notes: From Tables 2, 3, and 4 of O'Brien et al. Note that time column is different here than in published paper (which gives JD - 2440000 rather than JD - 2400000) to be consistent with optical data (below).

  • Reference: Dietrich, M., et al. 1998, ApJS, 115, 185 [Abstract]
  • Format of Data:
    • Column (1): JD - 2400000
    • Column (2): Flux. Continuum in units of 10^-15 ergs s^-1 cm^-2 Å^-1, emission lines in units of 10^-15 ergs s^-1 cm^-2.
    • Column (3): Uncertainty in flux, same units as column (2).
  • Additional Notes: The unbinned light curves are the complete light curves from the unpublished tables in tabular format.
    The time-binned versions are those used in the time-series analysis and displayed in Figures 1 and 4 of Dietrich et al. These are constructed by performing a weighted average of points within a 0.5-day window.
