Description
Results from ongoing calculations of the nucleon isovector electromagnetic form factors by the PNDME collaboration are presented. These are based on data from $\mathcal{O}(7000)$ configurations on two physical pion mass ensembles with $2+1+1$-flavor HISQ generated by the MILC collaboration at lattice spacings $a=0.087$ and $a=0.0576$ fm. We will discuss the extraction of the electric and magnetic form factors, focusing on the systematic improvements in the removal of excited-state contributions and the analysis of their $Q^2$ behavior.
