 r"""Perform a Y-Factor Calibration.
 Supports calculation of gain and noise figure for one or more channels using the
 Y-Factor method. Results are written to the file specified by the environment
-variable ``ONBOARD_CALIBRATION_FILE``. If the sensor already has a sensor calibration
+variable ``ONBOARD_SENSOR_CALIBRATION_FILE``. If the sensor already has a sensor calibration
 object, it is used as the starting point, and copied to a new onboard calibration object
 which is updated by this action. The sensor object's sensor calibration will be set to
 the updated onboard calibration object after this action is run.
