Performance of HAWC with the improved reconstruction algorithm

The High Altitude Water Cherenkov Gamma-ray Observatory (HAWC) has been operational since 2015 on the flanks of the Sierra Negra volcano, México. HAWC's reconstruction algorithm performance has been recently upgraded from Pass 4 to Pass 5. Improvements include gamma-hadron separation efficiency, especially for higher energy events, and angular resolution, with the most significant advancements for events from large zenith angles. Moreover, the reconstruction of air showers hitting a small fraction of the detector has been enhanced, which improves the low-energy resolution of HAWC despite the noise. Here, we show the effective area, angular resolution, and gamma-hadron separation efficiency as a function of primary gamma-ray energy and zenith angle in contrast to the Pass 4 performance.
