Manar, You can use either. You need to put in the Earth's Magnetic Field definition (Magnitude, Inclination, & Declination) at the measurement location. You can find these values by using the IGRF/DGRF tool. If you are modelling reduced to the pole data, use inclination=90 degrees, declination=0. Ideally you should use the magnitude from the original measurement location and time.
