  Searching for axion dark matter, the ADMX collaboration acquired data from
January to October 2018, over the mass range 2.81--3.31 $\mu$eV, corresponding
to the frequency range 680--790 MHz. Using an axion haloscope consisting of a
microwave cavity in a strong magnetic field, the ADMX experiment excluded
Dine-Fischler-Srednicki-Zhitnisky (DFSZ) axions at 100% dark matter density
over this entire frequency range, except for a few gaps due to mode crossings.
This paper explains the full ADMX analysis for Run 1B, motivating analysis
choices informed by details specific to this run.
