Calibration between Lidar and IMU

[doubleWIN39]

Hello, I am currently seeking to utilise the dataset you have published for my research. However, I have encountered trajectory divergence issues. This is due to the lack of known parameters between the IMU and other sensors. Would it be possible for you to provide these? The calibration parameters I am currently employing are as follows, but they appear to be incorrect.
extrin_calib:
# LiDAR 2 IMU
extrinsic_R: [-1.0, 0.0, 0.0,
0.0, -1.0, 0.0,
0.0, 0.0, 1.0]
extrinsic_T: [-0.45, 0.0, 0.20]
extrinsic_est_en: true
# LiDAR 2 Camera
# Quaternion [w: -0.50490835, x: 0.5115674, y: 0.49051429, z: -0.49270892]
Rcl: [ 0.0163, -0.9996, 0.0229,
0.0345, 0.0235, -0.9991,
0.9993, 0.0155, 0.0349]
Pcl: [0.09581, 0.04062, -0.16507]
I would be most grateful if you could advise on this matter.
