Optimization of EUSO-SPB2 Cherenkov telescope pointing software for gravitational wave neutrino sources

Observations of transient target of opportunity (ToO) astrophysical neutrino sources will reveal information about the environments of very high energy sources. Neutrinos can be detected by the up-going air showers that come from Earth-skimming tau neutrinos. Orbital and suborbital optical Cherenkov telescopes can be used to detect these showers. While point sources are straightforward to target as they drop below the Earth's limb, current localizations of gravitational wave sources that a good candidates for neutrino sources are not as well constrained. Presented here are telescope pointing strategies to optimize neutrino detection probabilities when the source locations are not well known, using current LIGO/Virgo/KAGRA events and parameters for the Extreme Universe Space Observatory on a Super-Pressure Balloon 2 (EUSO-SPB2) mission as examples.
