What is Meshroom cameraSensor.db entry for Raspberry Pi Camera Module 3 (newly available Jan 2023)?

Question

I am building a camera array for photogrammetry using the Raspberry Pi Camera Module 3 that is newly available in my area in January 2023. I use Meshroom for photogrammetry and it has a database with camera sensor information. I'll need to add a new line for this new camera!

The cameraSensors.db file from the newest Meshroom-2021.1.0 contains these lines for older Raspberry Pi cameras:

RaspberryPi;RP_imx219;3.6736;devicespecifications

RaspberryPi;RP_imx477;6.287;devicespecifications

RaspberryPi;RP_OV5647;3.6288;devicespecifications

Could someone please tell me what the line should read for the Raspberry Pi Camera Module 3 available in early 2023? My thought from the camera specs is immediately below, but maybe someone who knows can comment?

RaspberryPi;RP_imx708;6.45;devicespecifications

Thank you, DS

In the documentation of Meshroom it says on the page on adding a camera:

You can add your own Camera and Sensor by adding a new line to the camerasensor.db located in ..\Meshroom-2018.1.0\aliceVision\share\aliceVision\ (you can use any text editor). Before editing the database, close Meshroom. Edit and save the edited file.

The format is:

CameraMaker;CameraModel;SensorWidth(mm);source

As the sensor is indeed 6.45 mm wide (according to the specs) your suggestion seems correct:
