LIGO (Laser Interferometer Gravitational Wave Observatory) detectors are capable of detecting gravitational waves
created by collisions of massive stellar remnants moving at high accelerations (The IPAC Communications and
Education team 2021). Collisions of massive stellar remnants create electromagnetic waves that can reveal many
aspects of the remnants that collided. The EM community is attempting to use data from the LIGO instruments to
infer the location of the sources and view the sources across all electromagnetic wavelengths as shown from the efforts
from (LIGO Scientific Collaboration 2021). Gravitational wave detectors are poor at localizing mergers, making the
discovery of counterparts a challenging task. We will compare the Bayes factor and the False Alarm Rate as metrics
of classifying sources as astrophysical in low latency. We will improve the low latency data products that are provided
to EM observers in order to aid in the discovery more counterparts in the future.
