xyz_sm (Re), dipole tilt angle (deg)
,tilt_angle_60
Distance (Re) from s/c location to Fairfield1970 model neutral sheet position.<br/>
dZ = fairfield70(xyz_sm, tilt_angle),<br/> xyz_sm is the s/c SM coordinates (Re) and tilt angle is in degrees.<br/> Valid for y_sm < 15 Re.

Kp, MLT (deg), R (Re), dipole tilt angle (deg)
omni_kp,,,tilt_angle_60
Magnetic latitude of the neutral sheet (Lopez1990 model) <br/>
MLAT = lopez90(Kp, MLT, R, tilt_angle) <br/>
Kp is the 3-hour magnetic index, MLT the magnetic local time in degrees (MLT = 0° at midnight)
R is the radial distance in RE and dipole tilt angle in degrees
