LRM Slope Correction Attitude Monitoring
The echo attitude in LRM mode: the angle between the nadir vector and the echo point vector, from the slope correction of the LRM heights over ice sheets. 0 where no slope correction is applied (ie over ocean), which is excluded. Note: the product gives the units as radians, but the values (median ~0.1 over the flat Antarctic interior, where surface slopes are ~0.1 degrees) are consistent with degrees.
Only LRM mode measurements are used. Product values of 0 (not computed or not applied) are excluded.

Statistics use every 20 Hz measurement of the cycle within each area. Std Dev is the population standard deviation, RMS the root mean square.
