N2 - The Event Horizon Telescope (EHT) Collaboration has recently produced
the first resolved images of the central supermassive black hole in the
giant elliptical galaxy M87. Here we report on tests of the consistency
and accuracy of the general relativistic radiative transfer codes used
within the collaboration to model M87* and Sgr A*. We compare and
evaluate (1) deflection angles for equatorial null geodesics in a Kerr
spacetime; (2) images calculated from a series of simple, parameterized
matter distributions in the Kerr metric using simplified emissivities
and absorptivities; (3) for a subset of codes, images calculated from
general relativistic magnetohydrodynamics simulations using different
realistic synchrotron emissivities and absorptivities; (4) observables
for the 2017 configuration of EHT, including visibility amplitudes and
closure phases. The error in total flux is of order 1% when the codes
are run with production numerical parameters. The dominant source of
discrepancies for small camera distances is the location and detailed
setup of the software "camera" that each code uses to produce synthetic
images. We find that when numerical parameters are suitably chosen and
the camera is sufficiently far away the images converge and that for
given transfer coefficients, numerical uncertainties are unlikely to
limit parameter estimation for the current generation of EHT
observations. The purpose of this paper is to describe a verification
and comparison of EHT radiative transfer codes. It is not to verify EHT

images. We find that when numerical parameters are suitably chosen and
the camera is sufficiently far away the images converge and that for
given transfer coefficients, numerical uncertainties are unlikely to
limit parameter estimation for the current generation of EHT
observations. The purpose of this paper is to describe a verification
and comparison of EHT radiative transfer codes. It is not to verify EHT
models more generally.
