Description
An update on the measurement of handedness in Fermi Large Area Telescope (LAT) data is presented using more than 10 years of observations. Simulations are performed to study the uncertainty of the data, taking into account the structure of the exposure caused by the energy dependent instrument response and the observing profile, as well as the background from the interstellar medium. The uncertainties found from these simulations exceed that estimated previously by a large amount, rendering the signal seen in the Fermi-LAT data insignificant.
