Abstract

This catalog presents a sample of 229236 optically variable quasar candidates identified in the AllWISE and Pan-STARRS1 data releases at 2-sigma and 3-sigma variability levels. Mid-IR bands (3.4, 4.6, 12 and 22um) are selected from the AllWISE data release, and 5 optical bands (grizy) are from Pan-STARRS1. 127350 quasars are found to be variable at the 3-sigma level.
