Only getting Accelerometer data not gyroscope

[Arvind Pandit]

Hello
I am using this package to generate config file for the kalibr imu-camera calibration.
But when I run the package
rosrun allan_variance_ros allan_variance bags imu.config

and when I analyze the .csv file with
rosrun allan_variance_ros analysis.py --data allan_variance.csv

It only shows the Accelerometer values.
ACCELEROMETER:
X Velocity Random Walk: 0.00214 m/s/sqrt(s) 0.12869 m/s/sqrt(hr)
Y Velocity Random Walk: 0.00285 m/s/sqrt(s) 0.17109 m/s/sqrt(hr)
Z Velocity Random Walk: 0.00211 m/s/sqrt(s) 0.12644 m/s/sqrt(hr)
X Bias Instability: 0.00090 m/s^2 11706.92482 m/hr^2
Y Bias Instability: 0.00117 m/s^2 15211.83888 m/hr^2
Z Bias Instability: 0.00059 m/s^2 7607.42798 m/hr^2
X Accel Random Walk: 0.00058 m/s^2/sqrt(s)
Y Accel Random Walk: 0.00076 m/s^2/sqrt(s)
Z Accel Random Walk: 0.00039 m/s^2/sqrt(s)

What could be the problem ?
