From: Josip Pavic <Josip.Pavic@xxxxxxx>
[Why]
Current configuration 0 is just a placeholder, and final parameters needed.
Also, configuration 1 is expected to emulate ABM 2.1 but is too aggressive.
[How]
Redefine configuration 0 with the finalized parameters, and increase the
contrast gain of configuration 1 so that it properly emulates ABM 2.1.
