What is the maximum thrust in Newton of the iris model?

Hello everyone,

I am using the iris model in a gazebo simulation.
I want to publish a thrust with setpoint_raw/attitude but I currently have a thrust in Newtons but I need to send a normalized thrust so between 0 and 1. I therefore need to know the value of the maximum thrust in Newton in order to normalize my thrust command. Where or how can I find it?

Thank you in advance for your help!
