The Event Horizon Telescope (EHT) has released analyses of reconstructed
images of horizon-scale millimeter emission near the supermassive black hole at
the center of the M87 galaxy. Parts of the analyses made use of a large library
of synthetic black hole images and spectra, which were produced using numerical
general relativistic magnetohydrodynamics fluid simulations and polarized ray
tracing. In this article, we describe the PATOKA pipeline, which was used to
generate the Illinois contribution to the EHT simulation library. We begin by
describing the relevant accretion systems and radiative processes. We then
describe the details of the three numerical codes we use, iharm, ipole, and
igrmonty, paying particular attention to differences between the current
generation of the codes and the originally published versions. Finally, we
provide a brief overview of simulated data as produced by PATOKA and conclude
with a discussion of limitations and future directions.
