Can't find ArduCopter camera sensor size or any info

Hi all!
Where I can find the sensor size (width and height) of the drone virtual camera?

Include context on what you are trying to achieve

I’m trying to analyze images that I get from the bottom center camera (number 3), but I need to know the camera sensor size.

Context details

I’m using v1.8.1 - Linux AirSimNH as a virtual environment with Ardupilot ArduCopter.
Here’s my setting.json:
{
“SettingsVersion”:1.2,
“LogMessagesVisible”:true,
“SimMode”:“Multirotor”,
“Vehicles”:{
“Copter”:{
“VehicleType”:“ArduCopter”,
“UseSerial”:false,
“DefaultVehicleState”:“Armed”,
“LocalHostIp”:“127.0.0.1”,
“UdpIp”:“127.0.0.1”,
“UdpPort”:9003,
“ControlPort”:9002,
“AllowAPIAlways”: true,
}
},
“CameraDefaults”:{
“CaptureSettings”:[
{
“ImageType”:0,
“Width”:600,
“Height”:600,
“FOV_Degrees”:90,
“AutoExposureSpeed”:100,
“AutoExposureBias”:0,
“AutoExposureMaxBrightness”:0.64,
“AutoExposureMinBrightness”:0.03,
“MotionBlurAmount”:0,
“TargetGamma”:1.0,
“ProjectionMode”:“”,
“OrthoWidth”:10
}
],
“X”: 0, “Y”: 0, “Z”: 0,
“Pitch”: 0, “Roll”: 0, “Yaw”: 0
}
}

Include details of what you already did to find answers

I searched through airsim, unreal engine, and ardupilot projects for any information, but found only setup for cinematicCamera. But I’m not sure that it’s the correct camera used on copter…
