The AGORA disk initial conditions were generated as part of the AGORA comparison project, and have been used in a number of subsequent studies using many different simulation codes. Here you can find the initial conditions in the Tipsy format that is used by the ChaNGa and gasoline codes. The initial conditions for these are described in detail in Kim et al. 2016, "THE AGORA HIGH-RESOLUTION GALAXY SIMULATIONS COMPARISON PROJECT. II. ISOLATED DISK TEST"
The units in the ICs are as follows:
Velocity: km/s
Mass: 1e9 Msol
Length: kpc
