• misc/do_cal.py:28:CAL_MINMAX_FILE = os.environ['HOME'] + '/KSC.cal'
• misc/do_cal.py:29:CAL_DATA_FILE = os.environ['HOME'] + '/KSC_extended_calibration.csv'
• src/mobility/scripts/cal_imu.py:134: default='/home/swarmie/KSC_extended_calibration.csv'
• src/swarmie/launch/swarmie.xml:152: <param name="raw_data_path" value="/home/swarmie/KSC_extended_calibration.csv"/>
