Light curves of the 3C 390.3 nucleus from Sergeev et al. 2002, 2011, 2017. Description of files:

The below references point to the three-column ASCII files that contain light curves of the continua and spectral lines in 3C 390.3. The first column is JD-2440000, the second column is fluxes in units of 10-14 ergs cm-2 s-1 and 10-16 ergs cm-2 s-1 Å-1 for the lines and continua, respectively, and the third column is flux uncertainties in the same units. The continuum light curve at 5100Å consists of both the spectral and photometric (V filter) data.

Data files, integration zones, and mean relative uncertainties:

1. Contributions to the light curves from both the narrow lines and the host galaxy are NOT subtracted.
