  The ADMX collaboration gathered data for its Run 1A axion dark matter search
from January to June 2017, scanning with an axion haloscope over the frequency
range 645-680 MHz (2.66-2.81 ueV in axion mass) at DFSZ sensitivity. The
resulting axion search found no axion-like signals comprising all the dark
matter in the form of a virialized galactic halo over the entire frequency
range, implying lower bound exclusion limits at or below DFSZ coupling at the
90% confidence level. This paper presents expanded details of the axion search
analysis of Run 1A, including review of relevant experimental systems,
data-taking operations, preparation and interpretation of raw data, axion
search methodology, candidate handling, and final axion limits.
