Description of files

Photometric light curves for 14 AGNs are stored in the file data.tar.gz. This archive consists of 14 directories with the names in accordance to the names of the observed objects. Each directory has five light curves stored in five files: b.lc, v.lc, r.lc, r1.lc, and i.lc. The name of each file is the filter name: B, V, R, R1, and I, where filter R1 represents closely Cousin's filter I, while other filters represent closely respective Johnson's filters. Each file consists of some header for internal use and  three data columns:

  1. Heliocentric Julian Date minus 2450000.

  2. Object-to-comparison star ratio of fluxes, or: 10-0.4*m, where m is differential stellar magnitude between object and comparison star.

  3. Standard deviation (+/-1 sigma uncertainty).

 

Stellar magnitudes of the comparison stars according to Doroshenko et al. 2004 that were used in our paper to compute absolute magnitude in filter B:

Description of the Table columns:

  1. Object name

  2. Name of the comparison star for this object (internal designations, the same as in the paper by Doroshenko et al. 2004)

  3. Right Ascention of the comparison star for epoch 2000.0 (hh:mm:ss.s)

  4. Declination of the comparison star for epoch 2000.0 (+/-dd:mm:ss.s)

  5. Johnson's B magnitude of the comparison star

  6. Johnson's V magnitude of the comparison star

  7. Cousin's R magnitude of the comparison star

  8. Cousin's I magnitude of the comparison star
