Constructing the next-generation low-latency calibration pipeline for Advanced LIGO

We are soundly in the detection era of gravitational-wave physics with ground-based interferometric detectors, such as Advanced LIGO, Advanced Virgo, and KAGRA. To date, there are approximately 200 detections of gravitational waves from inspiraling binary systems. Calibration of the interferometric detectors is a critical step within the detection pipeline. It is increasingly important that we are able to produce accurately calibrated data in low latency.
Any astrophysical statements derived from calibrated strain data will inherit the systematic and statistical errors that result from the calibration procedures. Therefore, producing high-quality calibration allows for more accurate estimation of astrophysical parameters from detected events, such as sky position. Producing the calibrated strain data accurately in near-realtime allows us to inform other observatories about imminent mergers, allowing for further observation
The goal of our current work is to modernize the software used to produce near-realtime calibrated strain data to be better integrated into emerging low-latency data infrastructure, integrated with realtime monitoring of the fidelity of calibrated data products, and flexible enough to allow for modular developments of new calibration procedures.
