A new paper titled “BAYESIAN TIME DELAY INTERFEROMETRY” by Jessica Page (UAH) and Tyson Littenberg (ST12) was accepted for publication in Physical Review D. The study demonstrates a data-driven approach to the initial calibration processing of Laser Interferometer Space Antenna (LISA) data, effectively “self-calibrating” the data without need of the planned on-board inter-spacecraft ranging system. The algorithm, called Time Delay Interferometry Ranging (TDIR), is designed to be integrated into the “Global Fit” analysis pipeline under development by the MSFC gravitational wave research group.
A preprint of the paper is available at https://arxiv.org/abs/2107.08174.
