Estimation of error on the cross-correlation, phase and time lag between evenly sampled light curves

Misra, R.; Dewangan, G.; Bora, A.

Temporal analysis of radiation from Astrophysical sources like Active Galactic Nuclei, X-ray Binaries and Gamma-ray bursts provides information on the geometry and sizes of the emitting regions. Establishing that two light-curves in different energy bands are correlated, and measuring the phase and time-lag between them is an important and frequen…
