Units of reconstruction.json?

Hello there. Regarding the reconstruction.json file documentation, the explanation reads as follows:

reconstruction.json: [RECONSTRUCTION, ...]

RECONSTRUCTION: {
    "cameras": {
        CAMERA_ID: CAMERA,
        ...
    },
    "shots": {
        SHOT_ID: SHOT,
        ...
    },
    "points": {
        POINT_ID: POINT,
        ...
    }
}

CAMERA: {
    "projection_type": "perspective",  # Can be perspective, brown, fisheye or equirectangular
    "width": NUMBER,                   # Image width in pixels
    "height": NUMBER,                  # Image height in pixels

    # Depending on the projection type more parameters are stored.
    # These are the parameters of the perspective camera.
    "focal": NUMBER,                   # Estimated focal length
    "k1": NUMBER,                      # Estimated distortion coefficient
    "k2": NUMBER,                      # Estimated distortion coefficient
}

SHOT: {
    "camera": CAMERA_ID,
    "rotation": [X, Y, Z],      # Estimated rotation as an angle-axis vector
    "translation": [X, Y, Z],   # Estimated translation
    "gps_position": [X, Y, Z],  # GPS coordinates in the reconstruction reference frame
    "gps_dop": METERS,          # GPS accuracy in meters
    "orientation": NUMBER,      # EXIF orientation tag (can be 1, 3, 6 or 8)
    "capture_time": SECONDS     # Capture time as a UNIX timestamp
}

POINT: {
    "coordinates": [X, Y, Z],      # Estimated position of the point
    "color": [R, G, B],            # Color of the point
}

I was wondering if the units of the parameters of the camera could be specified. In fact, it would be convenient if all the units of the reconstruction.json file could be specified such as the ones for estimated translation as well. Would this be possible?

Start with the reconstruction file format section of the dataset documentation linked in the issue and review each listed field against the format's definitions. Update the documentation to state units for the camera and reconstruction parameters, including translation, and verify every parameter has an explicit unit or an explicit unitless designation.
