IceCube Second Track Data Release IceTracks-DR2: Data from 2008-2022 for Neutrino Source Searches

The events contained in this release make up the event sample commonly used for IceCube's time-integrated neutrino point source searches. Events in this sample are track-like neutrino candidates detected by IceCube between April 2008 and May 2022.<br>

<br>

This data release (referred to as "IceTracks-DR2") is an evolution of the previous 10-year version of this data sample that has been made publicly available here: https://doi.org/10.7910/DVN/VKL316 (referred to as "IceTracks-DR1"). In comparison with IceTracks-DR1, IceTracks-DR2 includes four additional years of data collected with the full IceCube detector configuration and incorporates improved calibrations. See [1] for more details. IceTracks-DR2 is intended to supersede IceTracks-DR1, and events from IceTracks-DR2 are not intended to be combined with other IceCube public data releases. <br>

<br>

Standardized checks of generic point source results using this sample (including results associated with notable astrophysical neutrino source candidates such as NGC 1068 and TXS 0506+056) have been compiled in [1]. <br>
