Table 2. KMAG data levels

Data level	Description
TM	Raw TM data as received at the ground receiving station (binary).
Raw (Level 0)	Converting TM data (binary) to ASCII format and scientific units.
PP (Level 1)	The orthogonality of the magnetometer sensor is corrected. In addition, zero-offset determination and coordinate transform are applied.
CAL (Level 2)	Research-grade. End-user level data products. This data is the final data calibrated for spacecraft-generated fields.

There are three levels of science data: Raw, PP, and CAL.
KMAG, Korea Pathfinder Lunar Orbiter Magnetometer; TM, science telemetry; PP, Partially Processed; CAL, Calibrated.
